Embodiment
In radio telecommunication application, the route of RF signal adopts the RF switch of relay-type electric mechanical switch or based semiconductor, for example transistor switch or diode switch conventionally.Relay switch is usually SPDT switch, and single input terminal is connected to any one in two lead-out terminals by it.
As shown in Figure 2, be an example circuit that " low " transmitted power level is provided to lead-out terminal (203,204) from input terminal (201,202).In this switch step, cited power combiner (208) does not engage.Both in the port of power combiner are connected to input terminal (201,202) via SPDT switch (205,206), one in port is connected to lead-out terminal (204) via SPDT switch (207), and the one in port for example, is connected to ground connection via termination resistor (209) (, 50 Ω).One (203) in output turns on and off via being directly connected to the SPDT switch (206) of input terminal (202).Circuit can provide " height " power stage and not export from another lead-out terminal (203) through switching with the one from lead-out terminal (204), as illustrated after the switching in Fig. 3.In Fig. 3, be switched to in the position from the transmitting power of input (301,302) and the output of the one (304) from lead-out terminal in illustrated power combiner (308) combination corresponding to the SPDT switch (305,306,307) of the switch in Fig. 2 (205,206,207).The SPDT switch (306) that one (303) in lead-out terminal has been associated by switching disconnects.In Fig. 2, a port of power combiner (308) for example, is connected to ground connection via termination resistor (309) (, 50 Ω).The switch (205-207,305-307) of Fig. 2 and Fig. 3 switches to realize results needed with the method for synchronization.Relay switch forms the class switch for switching as Fig. 2 and Fig. 3 of prior art.
Can be observed from Fig. 2 and Fig. 3, related to three SPDT switches.In the out of order situation of one in switch, control the desirable characteristics of transmitting power and may lose.The greater number of related switch also makes circuit board wiring become intensive.In the case of the loss of long electric wire or strip line and between coupling may be very large, this is especially a problem for the larger transmitted power level of radiofrequency signal.The advantage of relay switch is that it can be remotely controlled when needed.But the control (no matter whether being long-range) of relay switch need to be used for the wiring of closure/turn-off current and the additional surface area being associated (in the time installing) of printed circuit board (PCB) (PCB) thereon.Unless use bistable action repeater, otherwise during the steady state operation occurring without switching, electric control signal also increased the power consumption of final products.And repeater contact is especially due to the manufacture of relative complex and key Design and cost is higher.The quality of relay switch, not always corresponding to its high price, has significant cost thereby cause changing out of order switch, but also causes the reliability of overall product to reduce.Realize the related number of switches of desired function larger, the risk of at least one switch that is out of order is also larger, and therefore also just larger according to the risk of the circuit that is out of order of Fig. 2 or Fig. 3.
As mentioned, the particular problem joining with RF signal correction is loss.For power amplifier (PA) circuit, the conductor in the substantive output circuit that is partly identified as being derived from PA of loss.
Even if known relay switch has the good isolation between relatively little loss, terminal and is also applicable to large transmission power level, but occupy sizable area/volume of products obtained therefrom for the control circuit of repeater, and need when may having at least control signal electric current very large aspect power consumption.Along with the increase of frequency of operation, in order to meet the RF requirement in microwave frequency range, it is intensive that repeater contact structure often becomes.Transmission power level is larger, and the PCB area that relay switch needs is larger.The PCB area needing is larger, and the length of the PCB conductor length of adjacency is inevitably larger.Be associated with larger conductor length, it is larger that power loss becomes.
The certain benefits of relay switch is, in the time being arranged in electromagnetic shield or anti-gray/waterproof seal, it is still changeable and can not destroy seal.Also can have specific climatic environment over cap, for example, prevent direct sunlight or for cooling, even if it does not frequently change, but will be also only consuming time for switching circuit being set in to dismounting and refitting in action required pattern.In particular, this kind dismantled and refitting can reduce and be associated with performance, unless retained modestly sealing and environmental protection.In fact keep equally this advantage for the diode and the transistor switch that are referred to as semiconductor switch.
And semiconductor switch provides some difficult problems.For semiconductor switch, be very difficult to realize low-loss, high degree of isolation and high power transfer capability simultaneously.In order to transmit larger power level, required PCB area is large and also may be larger for the required power consumption of the electric control of semiconductor switch.In high power RF application, the reliability of semiconductor switch may be also problem, and it causes the larger cost of the device that depends on these switches and bad functional.
The most useful prior art manual operation switch need to be dismantled electromagnetism lid in the weather security context that not affected by for example rain and dust, and it originally will affect equipment dependability or performance.
Notice, the block diagram in Fig. 2 or Fig. 3 depends on the switching according to SPDT owing to intensive wiring.Point out for embodiments of the invention, can be regarded as the switching of the technology of the expansion of DPDT by depending on basis, the amount of PCB layout/strip line reduces substantially.The corresponding block diagram switching schematically comprises and adds a DPST (411-420) as schematically illustrate in Fig. 4 DPDT (401-410).DPDT part (401-410) respective input (401,402) is connected to two in the middle of any one in lead-out terminals (405,406), (407,408), comprising it is in order to understand and completely corresponding to according to the DPDT of Fig. 1 (130).Middle lead-out terminal (405-408) is interconnected to lead-out terminal (403,404).Therefore the Input output Relationship between the input of the Part I of commutation circuit figure and output port (401,402,403,404) is corresponding to the corresponding part of embodiment.The DPST part (411-420) of Fig. 4 is in fact corresponding to Fig. 1 (120), because imaginary terminal (416,417) is only off-state.Arrive lead-out terminal (413,414) from imaginary lead-out terminal (415,418) and do not need extra interconnection.Compare with DPDT (130) with the SPDT (120) of Fig. 1, the switch contact (409,410,419,420) of the expansion of Fig. 4 is all synchronous in operation according to embodiment.
