Description

For operating the technology of millimeter wqve radio mould phased array antenna in the block
Cross reference to related applications
The equity of U.S. Provisional Application No.61/843,741 submitted this application claims on July 8th, 2013.
Technical field
The present invention relates generally to mm wave RF (RF) system, and more particularly to such radio module in for allowing height Imitate the operation for the phased array antenna that signal is propagated.
Background
60GHz frequency bands are the unlicensed frequency bands characterized by big amount of bandwidth and the big whole world are overlapping.Big bandwidth means very A large amount of information can be transmitted wirelessly.As a result, respectively multiple applications of requirement transmission mass data can be developed to allow to enclose Wireless communication around 60GHz frequency bands.The example of such application includes but not limited to:WirelessHD TV (HDTV), wireless depressed place It stands, wireless Gigabit Ethernet and many other applications.
In order to facilitate such application, need to develop the integrated circuit (IC) operated in 60GHz frequency ranges, such as amplify Device, frequency mixer, radio frequency (RF) analog circuit and active antenna.RF systems generally include active and passive module.Active module embedded therein (for example, phased array antenna) needs that signal and power signal is controlled to carry out its operation, and these signals are passive module (examples Such as, wave filter) institute it is unwanted.Various modules are manufactured and are encapsulated as RF IC (RFIC), and RFIC can be assembled On printed circuit board (PCB).The range of RFIC package sizes can be from several square millimeters to hundreds of square millimeter.
In consumer electronics market, design and the thus design to wherein integrated RF modules to electronic equipment The constraint of minimum cost, size, power consumption and weight should be met.The design of RF modules should also be considered electronic equipment and especially It is the current assembling configuration of handheld device (such as on knee and tablet computer), enables to realize the height of millimeter-wave signal Effect transmission and reception.In addition, the minimum power that the design of RF modules should be counted and be received and transmit RF signals is lost and counts And maximum wireless electricity covering.
The schematic diagram of the RF modules 100 of transmission and the reception designed for millimeter-wave signal is shown in Fig. 1.RF modules 100 include being connected to RF circuit systems or active antenna (110-1 to 110-N) array of IC 120.Active antenna 110-1 is arrived Each antenna in 110-N can be used as transmitting (TX) and/or receive (RX) antenna to operate.Active antenna can be controlled to Radio signal is received/emitted in particular directions to perform beam forming and be switched to emission mode from reception pattern.Example Such as, active antenna can be phased array antenna, wherein each radiating doublet can be by individually and independently control so that energy Enough use beam forming technique.
In emission mode, RF circuit systems 120 generally using frequency mixer (not shown in FIG. 1) come perform up-conversion with Intermediate frequency (IF) signal is converted into radio frequency (RF) signal.Then, RF circuit systems 120 are sent out according to control signal by TX antennas Penetrate RF signals.In a receive mode, RF circuit systems 120 are received RF signals by active RX antennas and are held using frequency mixer It exercises and uses down coversion of local oscillator (LO) signal to IF signals, and IF signals are sent to baseband module (not shown in FIG. 1).
In receiving and transmitting mode the two, the operation of RF circuit systems 120 is controlled by baseband module using control signal System.The control signal be used for such as gain control, RX/TX switching, power level control, beam steering operation and etc. Function.In particular configurations, baseband module also generates LO signals and power signal, and such signal is transmitted to RF circuits system System 120.These power signals are to the DC voltage signal of the various assemblies power supply of RF circuit systems 120.Under normal circumstances, IF believes It number is also transmitted between baseband module and RF circuit systems 120.
In general design technology, active antenna (110-1 to 110-N) array is implemented in thereon also equipped with RF circuits On the substrate of the IC of system.IC is manufactured on multiple field substrate and the metal throuth hole connected between the layers.Multiple field substrate Can be the combination of metal and dielectric layer and can be by being such as laminated (for example, FR4 glass epoxy resins, bismaleimide Triazine), ceramic (for example, low-temperature co-fired ceramics LTCC), polymer (for example, polyimides), based on PTFE (polytetrafluoroethylene (PTFE)) Composition (such as PTFE/ ceramics, PTFE/ woven fiberglass) and Woven glass reinforcing material (for example, Woven glass Strengthen resin), wafer-class encapsulation and other encapsulation, technology and materials are made.The cost of multiple field substrate is the area of layer Function;The area of layer is bigger, and the cost of substrate is higher.
The antenna oscillator of active antenna (110-1 to 110-N) array in multiple field substrate generally by having metal figure Case is realized.Each antenna oscillator can utilize several substrate layers.In the conventional realization for millimetre-wave attenuator, antenna shakes Son is designed to occupy the unilateral side of multilager base plate side.It is in order to which aerial radiation is allowed correctly to be propagated to perform in this way.
In the conventional design of RF systems, active antenna 110-1 to 110-N is phased array.Phased array antenna provide by The wave beam of many antenna oscillators focuses on ability in the direction indicated.That is, phased array antenna is as they are individual antenna Action.
Connection between phased array antenna oscillator is usually unified into list by using by the feeding from all antenna oscillators The adder components of a feeding perform.The adder components can work along the various positions of feeding.From base band to The feed path (in this way, frequency along the signal of the feed path) of RF modules can be changed to RF frequency from IF.
The conventional of phased array realizes the array for generally comprising same antenna oscillator.Each antenna oscillator is independently by adjustable The control of control is saved, this, which is adjustably controlled, adjusts the feeding of the antenna oscillator mutually to coordinate with remaining antenna oscillator.Therefore, it is overall Wave beam is focused in particular directions or creates particular beam shape.
Because these antenna oscillator is identical, knows that this is adjustably controlled and independent phase is being fed with to each oscillator It is optimal in the case of the control of position.
As shown in Figure 2, conventional phased array antenna (is hereafter individually known as shaking using identical oscillator 210-1 to 210-4 Son 210 is collectively referred to as oscillator 210).The direction that signal is propagated is for the roughly the same gain of each 210 output of oscillator, and oscillator 210 phase is different.
In very high frequency (for example, between 30GHz and 300GHz), conventional phased array antenna is to use and lower frequency In identical principle realize.
The limitation that there is the antenna oscillator close to omnidirectional radiation pattern to have fundamentally is generated in very high frequency.This meaning Each oscillator in conventional phased array antenna has the feature of narrow beam width.For example, with the paster antenna more than 4dBi Oscillator may not focus on well with the ground dipole element more than 2dBi.With having for N number of identical oscillator The conventional phased array antenna use of 10log (N)+5dBi gains can be configured to what is focused on well in the 5dBi oscillator figures of individual Phased array carrys out result realization.
High frequency diffraction Bobbi low-frequency transmission introduces more losses.Therefore, the ability pair of efficient transmission in all directions Design criteria is important for the aerial array operated in high frequency.The conventional design of phased array antenna is for example as a result, As the millimeter-wave signal at 60GHz frequency bands transmission for be inefficiency.
Therefore it provides the technical solution for improving the operation of phased array antenna will be beneficial.

In S610, gain G i and phase the Φ i of each radiating doublet 510 are measured.On the one hand, the measurement is in beam forming It is performed during process.In order to measure gain G i and phase Φ i, transmitter to want controlled phased array antenna (for example, Antenna 500) receiver persistently emit (repetitive sequence) signal.Gain G i and phase Φ i can be as the another of communication link The function of the physical direction D of side and polarization is measured.Physical direction D and polarization because of the movement in transmitter or receiver and It rotates and changes.
Receiver opens a radiating doublet (for example, oscillator 510-1) and closes other radiating doublets (for example, oscillator 510-2 to 510-N).The operation is performed for each radiating doublet.For each oscillator of unlatching, receiver measurement receives signal Phase and amplitude.Measure gain G i and phase the Φ i that information is used as corresponding oscillator.On the one hand, all oscillators measure increasing Beneficial Gi and phase Φ i are saved in controller 570.In addition, these measurements can also be sent to transmitter.
For measuring the IEEE that the example process of gain G i and phase Φ i are also ratified and published on May 20th, 2010 It is discussed in the PHY/MAC specifications of 802.11ad standards (also referred to as WiGi).On the one hand, gain G i and phase Φ i are utilized The feeding of corresponding oscillator is controlled during the reception or transmission in signal.
In S620, two configurable parameters α and β have been selected.Parameter alpha and β be used to calculate feeding gain and phase Ai and θ I, it is proportional to the antenna gain Gi and phase Φ i measured.On the one hand, the value of α and β is randomly selected.In the opposing party The value of face, α and β are determined so as to make phase quantization and minimize the error.Generally, its of the accuracy of beam steering and radiation diagram The phase that his attribute depends on radiating doublet is fed.Phase quantization error affects phase feeding, and reduces error permission Improved antenna performance.
On the one hand, α and β value are configured to the range of pre-configured value, and phase quantization error is measured.Selection provides The α of minimum degree error and the setting of β value.
In S630, the feeding gain of each radiating doublet and phase (Ai;θ i, i=1 ..., N) based on these parameters and The antenna gain and phase (Gi measured;Φ i, i=1 .., N) it is individually determined.On the one hand, using configurable parameter α Feeding gain and phase are determined with β.
On the one hand, individual oscillator feeding gain and phase value Ai;θ i can be determined that feeding gain with array and Phase is proportional.On the one hand, the optimal value of array feeding gain A i and phase theta i can be determined that the function in direction.This is really Surely can be by using predetermined equation, such as formula 1 and 2 etc is completed, as shown below:
Ai=∝ Gi formulas 1
θ i=- φ i+ β formulas 2
Gi, Φ i, α and β are as defined above.
The maximum power in transmitter is provided using formula 1 and 2 illustrated above come the feeding gain calculated and phase to imitate Optimal appointment in minimal noise meaning at rate and receiver.On the one hand, phase can be by being seen with lower inequality It examines:
Formula 3
As θ i=- φ i+ β, formula 3 reaches equal.
The another aspect of the value of setting Ai and θ i can be determined using following formula:
Formula 4
If Ai=∝ Gi, formula 4 reach equal.On the one hand, use formula 3 or formula 4 that array gain is set to cause secondary lobe It minimizes.On the other hand, the secondary lobe of radiating doublet can be minimized for example, by non-convex optimization algorithm.Such algorithm energy Enough gains caused on required direction maximize, and to minimize on other directions or other specific directions return to zero. The operation of non-convex optimization and similar algorithm is effective because these radiating doublets (510) are different, and thus they Corresponding gain G i values are different.In addition, feeding gain A i is independently controlled.
On the other hand, the value of feeding gain A i and phase theta i can be determined that as far as possible closest to optimal value Value.Can be determined based on following formula θ i as far as possible closest to optimal value:
Formula 5
Can based on following formula come determine Ai as far as possible closest to optimal value:
Formula 6
On the one hand, either exhaustive search can be used to solve for formula 5, formula 6 or the two to Monte-Carlo methods.
In this aspect, if the control realized is inefficiency or can not additionally reach feeding gain A i and phase The optimal value of position θ i, then feeding the value of gain A i and phase theta i can be determined to be as far as possible closest to the value of optimal value.This is not Optimal value, which can be reached, to be occurred due to for example controlling gain mismatch in quantization, amplifier architecture, chain etc..
On the other hand, in order to save power, one or more complete chain in array can be closed.Preferably, The chain of such closing is the chain for having lowest gain value Gi.Close with compared with low gain specific chain allow save power and simultaneously It is minimum degree to make performance degradation.At such aspect, in S640, determine which chain or which chain will be closed.It will be closed The chain closed can by the chain of predetermined number of the (but not limited to) with lowest gain value Gi, with the overall gain value below threshold value Any number of chain etc. determine.
On the other hand, any or all oscillators feeding gain A i can pass through the arbitrary shape for changing changed oscillator Gain constant α is changed.The modification can occur for example, by the amplification for the gain for changing oscillator.At such aspect, reduce Parameter alpha will reduce the power consumption in array, because all amplifiers tend to consume less power for relatively low yield value.
In S650, the gain of each oscillator in array and phase are feeding yield value Ai and phase based on each oscillator Place value θ i and be set independently.It should be noted that at all of above aspect, when should realize balanced-to-unblanced transformer work( During energy, the feeding of one of antenna is configured to θ i, and another is configured to θ i+180 °.
