Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.
Based on the embodiment in the present invention, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
The open a kind of handheld device of the present invention, has higher transmitting chain efficiency and bandwidth, and its
The area penetrating link is less.
See the structural representation that Fig. 1, Fig. 1 are a kind of handheld device disclosed by the invention.This handheld device
Including battery unit 1, battery management unit 2, digital processing element 3, GaN radio-frequency power amplifier 4,
Antenna 5 and transmitter 6.
Wherein:
GaN radio-frequency power amplifier 4 is connected with transmitter 6, antenna 5 and digital processing element 3 respectively.
Transmitter 6 is connected with digital processing element 3.
Battery unit 1 includes multiple battery.The electricity that battery in battery unit 1 provides under series connection
Pressure is not less than the maximum working voltage of GaN radio-frequency power amplifier 4.Preferably, can be by electricity
The voltage that the battery that pool unit 1 is configured that in battery unit 1 provides under series connection is not less than GaN
The safe voltage (such as 36V) of the maximum working voltage of radio-frequency power amplifier 4 and no more than human body.
Battery management unit 2 is connected with digital processing element 3 and battery unit 1 respectively, battery management
Unit 2 has the first supplying channels, battery management unit 2 under the control of digital processing element 3, root
The connection in series-parallel relation of battery in battery unit 1 is adjusted according to the power demands of GaN radio-frequency power amplifier 4,

GaN material is third generation semi-conducting material, its have bigger energy gap, high breakdown field strength,
High mobility and the characteristic of high current density, the radio-frequency power amplifier made by GaN material has height
Power density, efficient, high reliability and the characteristic in broadband.
The output equivalent electric capacity Cds of GaN radio-frequency power amplifier is smaller, the magnitude of the most several pF.With
Si (silicon) material is compared with the radio-frequency power amplifier of GaAs (GaAs) material, GaN radio-frequency power
The output resistance Rout of amplifier can be much smaller with the variable quantity that frequency increases, and GaN radio-frequency power is put simultaneously
The switch response time of big device is the shortest, and therefore application GaN radio-frequency power amplifier is as in handheld device
Power amplifier, the efficiency of close power amplifier can be greatly improved, such that it is able to improve handheld device efficiency.
It addition, GaN material is compared with GaAs material, there is higher power density properties, therefore GaN
Radio-frequency power amplifier is in the case of using less area, it becomes possible to reach the merit required by handheld device
Rate ability.Meanwhile, GaN material has broadband character, just uses less GaN radio-frequency power amplifier
Multiband can be covered, reduce the area of the transmitting chain of handheld device.
GaN radio-frequency power amplifier needs to work under 10-40V, could efficient, high power density,
Broadband character is brought into play.Power supply in existing handheld device is low-tension supply (usually 3.3V),
If using boost module directly the low-tension supply of 3.3V to be boosted to 36V, boosting ratio is up to 11
Times, the defect of two aspects can be there is: 1) increase radio frequency link area.Due to opening in boost module
Close pipe otherwise to stop switching in switch transformation process, therefore there will be dv/dt component and di/dt component,
These components can produce the big transient voltage value to supply voltage 2-3 times, and it is high that switching tube is required to bear this
Pressure, in order to improve the voltage endurance capability of switching tube, switching tube needs the biggest area.Meanwhile, need to increase
Prevent the auxiliary circuit of EMI (electromagnetic interference), so can increase radio frequency link area.2) inefficient.
Switching tube in boost module there will be the highest dv/dt component and di/dt component in switching process, these
Component can increase switching loss, and the conversion efficiency causing power supply is relatively low, thus reduces the efficiency of whole system.
And handheld device disclosed by the invention, adjust battery in battery unit 1 by battery management unit 2
Connection in series-parallel relation, output and the power supply of GaN radio-frequency power amplifier 4 adaptation, the loss of electric energy is less,
The efficiency of whole system can be improved.It addition, what the switching tube in handheld device disclosed by the invention bore
Voltage is the supply voltage after battery series-parallel connection, switch will not produce in the handover high dv/dt component and
Di/dt component, therefore can use the switching tube that area is less, and prevent EMI's also without arranging
Auxiliary circuit, can reduce the area of transmitting chain.
Handheld device disclosed by the invention includes GaN radio-frequency power amplifier, battery unit, battery management
Unit, digital processing element, transmitter and antenna, battery management unit is in the control of digital processing element
Under, adjust the connection in series-parallel relation of battery in battery unit according to the power demands of GaN radio-frequency power amplifier,
Thus the voltage that can dynamically change is provided for GaN radio-frequency power amplifier by the first supplying channels.This
The handheld device of disclosure of the invention, uses GaN radio-frequency power amplifier, therefore, it is possible to improve handheld device
The bandwidth of transmitting chain, and owing to GaN radio-frequency power amplifier has higher efficiency, therefore, it is possible to
Improve the efficiency of the transmitting chain of handheld device；It addition, handheld device is by adjusting battery in battery unit
Connection in series-parallel relation be that GaN radio-frequency power amplifier provides adaptive supply voltage, it is possible to give full play to
The efficient performance of GaN radio-frequency power amplifier, and the loss of electric energy is less, can improve whole system
Efficiency；Meanwhile, the voltage that the switching tube in handheld device disclosed by the invention bears is battery series-parallel connection
After supply voltage, switch switching in will not produce high dv/dt component and di/dt component, therefore can adopt
With the less switching tube of area, it is not required that arrange and prevent the auxiliary circuit of EMI, and GaN radio frequency merit
The area of rate amplifier is less, therefore, it is possible to reduce the area of transmitting chain.
In concrete application, when handheld device communication distance farther out time, GaN radio-frequency power amplifier 4 needs
The supply voltage wanted is higher, the part or all of electricity during now Power Management Unit 2 controls battery unit 1
Connecting in pond, thus provides corresponding high voltage to GaN radio-frequency power amplifier 4.When leading to of handheld device
When communication distance is nearer, the supply voltage that GaN radio-frequency power amplifier 4 needs is relatively low, now power management
Unit 2 controls the cell parallel in battery unit 1, thus provides phase to GaN radio-frequency power amplifier 4
The low-voltage answered, also makes electricity use the time to maximize simultaneously.
Preferably, the optimum operating voltage of GaN radio-frequency power amplifier 4 is with its output
Change and dynamically change.When the output of GaN radio-frequency power amplifier 4 is bigger, GaN radio frequency merit
The running voltage of rate amplifier 4 is bigger numerical value, at the output of GaN radio-frequency power amplifier 4
Time less, the running voltage of GaN radio-frequency power amplifier 4 is less numerical value.
