Definitions
- the present invention generally relates to electronic circuits and, more particularly, radiofrequency couplers.
- the invention more particularly relates to a dual-band coupler (Dual Coupler).
- a coupler is generally used to take a portion of the power present on a transmission line, called primary or primary, to another line, called coupled or secondary, located nearby.
- the couplers are divided into two categories depending on whether they consist of discrete passive components (this is called a localized element coupler) or conductive lines close to each other to be coupled (this is called a line coupler). distributed).
- the invention relates to the second category of couplers.
- a dual-band coupler shares measurement ports between two transmission lines for carrying signals in two different frequency bands. Such sharing is possible in any dual-band system where the frequency bands are not used simultaneously. This is generally the case for radiofrequency applications (for example, mobile telephony for a bi, tri or quad-band telephone, WiFi, etc.).
- a dual-band coupler makes it possible, for example, to share the same control or amplification circuit for two transmission channels.
- the antennas connected at the output of the two main lines introduce additional coupling.
- the greater this coupling the less good the isolation between the two antennas, the more the results of the measurement are distorted.
- the coupler is not sufficiently selective in frequency of one channel with respect to the other.
- US-A-2005/0239421 discloses a capacitive compensated directional bi-band coupler.

- a first diplexer connecting the second and fourth ports, the respective ends of the second and fourth lines to a fifth port;
- a resistive divider or a second diplexer connecting the first and third ports, the respective ends of the second and fourth lines to a sixth port.

- a second diplexer connects, on the first and third ports, the respective ends of the second and fourth lines to a sixth port.

- FIG. 1 is a block diagram of a radiofrequency transmission line using a two-band coupler of the type to which the present invention applies by way of example.
- An emission circuit 11 sends a radio frequency signal to be transmitted.
- a 12L or 12H (PA) amplifier is selected according to the frequency band used.
- a first channel intended for a frequency band signal
- TxL relatively low (compared to the other band of the system) and operating a 12L amplifier (PA), and a second channel intended for a relatively high frequency band (TxH signal) (higher than the frequencies of the other band) operating a 12H amplifier.
- the respective outputs of the amplifiers 12L and 12H are intended to be connected to antennas 13L and 13H.
- a coupler 1 is interposed between the respective outputs of the amplifiers 12L and 12H and the antennas 13L and 13H, where appropriate with the interposition of a channel splitter 14 (SPLIT) for distinguishing the reception and reception stream transmissions RxL.
- SPLIT channel splitter 14
- a first main line of the coupler 1 is interposed between the output of the amplifier 12L and the antenna 13L.
- An access port 11%, said low frequency input is 12L amplifier side while an access port ⁇ % (sometimes also designated DIR), said low frequency output, is 13L antenna side.
- a second main line of the coupler 1 is interposed between the output of the amplifier 12H and the antenna 13H.
- An 11% access port, called high frequency input, is on the 12H amplifier side while an access port OR% (or DIi%), said high frequency output, is 13H antenna side.
- One or more coupled or secondary lines of the coupler take some of the power of the main lines.
- CPLD and ISO measurement ports respectively connected to one side and the other of the secondary line (s) provide information on, for example, the signal strength. transmitted, losses due to antenna mismatch, etc.
- measurements are provided to a circuit (CTRL) for controlling the gain of the 12L or 12H amplifier used.
- CTRL circuit for controlling the gain of the 12L or 12H amplifier used.
- a coupler is defined, inter alia, by its direc ⁇ tivity which represents the difference in power (expressed in dB) between the two ports of its coupled or secondary line, all the other ports being loaded by an impedance of 50 ohms.
- An ideal coupler has an infinite directivity, that is to say that no power is present on the ISO port of its line secondary signal next to the OUT port of its main line when a signal is traveling on that main line from the input port to that output port.
- a coupler is said directive when its directivity is sufficient for the powers recovered on the ports of its secondary line to distinguish the direction of flow of power in the main line.
- the embodiments that will be described relate to the directional couplers in which the signals present on the CPLD and ISO terminals do not have the same levels. If these couplers are symmetrical, then they are bidirectional, that is, in the same way that a signal applied to the IN terminal is coupled to the CPLD terminal, a signal applied to the OUT terminal is coupled to the level of the ISO terminal.
- Figure 2 is a schematic view of a two-band coupler in distributed lines.
- a first main line 2L of the coupler 1 intended to be interposed on a radio frequency transmission line (low frequency band), is directly connected to two ports or terminals ⁇ 3 ⁇ 4 ⁇ and OUT ⁇ g respectively input and output.
- a second main line 2H intended to be interposed on another radio frequency transmission line (high frequency band), is directly connected to two ports or terminals I3 ⁇ 4B and OUT ⁇ g respectively input and output.
- a secondary line 3, for example interposed between the two main lines, comprises two ports or terminals respectively CPLD and ISO, and is intended to convey information proportional to the power transmitted in the main line used.
- the lines 2L, 2H and 3 are, in practice, formed of conductive tracks carried by an insulating substrate.
- the lengths of the lines depend on the desired operating frequency.
- lines 2L and 2H have been represented with the same length but are in practice of different length.
- the width of the lines depends on the directivity and the characteristic impedance sought.
- the coupler of FIG. 2 is directional, the signals present on the CPLD and ISO ports not having the same levels. Such a coupler is however symmetrical, which makes it bidirectional. In a directional and symmetrical coupler as shown in FIG. 2, the roles of the terminals are defined by the connections of the coupler to the other elements.
- the main parameters of a coupler are: insertion losses which represent the transmission loss between the two accesses of a main line (the insertion losses are defined while the other two ports of the coupler are loaded by an impedance 50 ohms);
- the coupling which represents the transmission loss between the IN and CPLD ports (the coupling is defined while the other two ports OUT and ISO are loaded by a 50 ohms impedance);
- the isolation which represents the transmission loss between the IN and ISO ports (the isolation is defined while the other two ports OUT and CPLD are loaded by a impedance of 50 ohms);
- the coupler is driven by a low frequency signal on the terminal ⁇ 3 ⁇ 4 ⁇ .
- a small part of the signal (whose power depends on the coupling) is found on the CPLD terminal.
- a coupler is considered to have a good directivity if it is at least 20 dB. With a coupling of about -30 dB (which corresponds to taking 1/1000 of the transmitted power), the insulation is then of the order of -50 dB, which is acceptable and a small part of the signal is found on the ISO terminal.
- the 13L antenna absorbs the entire signal without producing reflection. This corresponds to the operation of a simple coupler.
- the isolation between the antennas 13L and 13H is not perfect and a coupling (arrow 24) appears between the two antennas.
- a spurious signal is therefore sent by the antenna 13H for high frequencies (arrow 25) to the terminal OU ⁇ g of the coupler.
- Part of this reflected signal is coupled to the ISO terminal (arrow 26).
- This parasitic coupling degrades the performance of the coupler and especially distorts the measurement on the ISO terminal, thus the measurement of the losses in reflection (difference between the powers present on the terminals CPLD and ISO).
- Figure 3 shows another embodiment of a dual-band coupler, equipped with attenuators.
- conductive tracks 3L and 3H participate in the production of secondary lines respectively dedicated to the main lines 2L and 2H.
- the respective ends of the secondary lines 3L and 3H are, on the CPLD terminal side, connected by a resistive separator 4 j .
- These lines are connected, on the ISO terminal side, by a resistive separator 4Q.
- Each separator is formed of three resistors R1, R2 and R3.
- Two resistors R1 and R2 are in series between the respective ends of the lines 3L and 3H ( ⁇ 3 ⁇ 4 ⁇ and INHB for the separator 4 j and OUT ⁇ g and OUT ⁇ g for the separator 4Q) and a third resistor R3 connects the midpoint of this series association to the terminal CPLD, respectively ISO.
- FIG. 4 represents an embodiment of a dual-band coupler 1 preserving the directivity of the coupler.
- the separator 4Q on the ISO terminal side is replaced by a diplexer 5, that is to say a low-pass filter on the line side 3L associated with a high-pass filter line side 3H.
- the objective is to filter the signals received by the unused antenna in the transmission.
- circuit Q is a diplexer whose function is to separate two frequency bands distant from each other.
- FIG. 5 illustrates an example of diplexer 5 Q of the response curve of Figure 4. It is assumed arbitrarily introducing a diplexer 8 dB of insertion loss (to balance with the separator 4 j side terminal CPLD that also introduces an attenuation 8 dB).
- FIG. 5 illustrates an example of diplexer 5 Q of the response curve of Figure 4. It is assumed arbitrarily introducing a diplexer 8 dB of insertion loss (to balance with the separator 4 j side terminal CPLD that also introduces an attenuation 8 dB).
- FIG. 5 illustrates an example of application to mobile telephony in which the low frequency band LF is around 800 MHz and the high frequency band HF is around 2.2 GHz.
- the LP channel of the diplexer passes between the end of the line 3L and the ISO terminal, the low frequencies and cuts the high frequencies while the HP channel, between the end of the line 3H and the ISO terminal, cuts the low frequencies to pass frequencies in the 2.2 GHz band.
- the numerical example of FIG. 5 is arbitrary and the person skilled in the art will be able to adapt the diplexer 5 as a function of the frequency bands to be processed by the coupler.
- a similar operation occurs by driving the coupler through the line 2H with a signal in the high frequency band, the insulation fault between the two antennas being filtered by the diplexer 5.
- the diplexer is preferably sized to have attenuation corresponding to that of the attenuator 4 j side CPLD terminal.
- FIG. 6 represents another embodiment in which a second diplexer 5 j is provided on the CPLD terminal side in place of the attenuator 4 j .
- a second diplexer 5 j is provided on the CPLD terminal side in place of the attenuator 4 j .
- Such an embodiment makes the symmetrical coupler, so bidirectional, unlike the assembly of Figure 4 which is not symmetrical.
- FIG. 7 represents a first exemplary embodiment of a diplexer that can be used in the coupler of FIGS. 4 and 6.
- a first branch between the ISO terminal and the end of line 3L forms a low-pass filter of order 3.
- Three inductors LU, L12 and L13 are in series and the middle points of this series association are directly connected to the mass by capacitors, respectively Cil and C12.
- a second branch between the ISO terminal and the end of the line 3H forms a high-pass filter of order 3.
- Three capacitors C21, C22 and C23 are in series and the middle points of this series association are directly connected to the mass by inductances, respectively L21 and L22.
- FIG. 8 represents another embodiment of a diplexer that can be used in the embodiments of FIGS. 4 and 6.
- the inductances LU, L12, L13, L21 and L22 are replaced by resistors, respectively R11, R12, R13, R21 and R22.
- inductive or resistive elements depends, for example, on the available technology and, in particular, the possibility of easily integrating inductive elements into this technology.
- the low-pass and high-pass filters forming the diplexers are at least 2-order and preferably 3-order.
- Figure 9 shows a coupler according to yet another embodiment.
- each secondary line 3L, 3H is interrupted approximately in the middle to form two sections.
- the ends of the sections that face each other are each connected to the ground by an attenuator.
- each secondary line comprises two sections 31L, 32 ⁇ and 313 ⁇ 4, 32 ⁇ parallel to lines 2 ⁇ and 2 ⁇ .
