【0010】前述のように、第2及び第3の送受コンバイナTRC 2及びTRC 3においては送受コンバイナを構成する送信用帯域通過ろ波器TBPF側の入出力端子T Tを除く他の端子、即ち、共通の入出力端子T C及び受信用帯域通過ろ波器RBPF側の入出力端子T Rとの各入出力結合を容量結合とする他は、段間結合を容量結合又は磁気結合の何れによって結合させても本発明を実施できるが、第1ないし第3の送受コンバイナTRC 1ないしTRC 3を構成する受信用帯域通過ろ波器RBPF及び送信用帯域通過ろ波器TBPFの各通過域における中心周波数(共振周波数)と各段間結合態様との関係を、以下述べるように選定することによって、送受コンバイナを小型に構成し、挿入損失を小さくすることができる。 [0010] As described above, the second and third other terminal except the input and output terminals T T of the transmission band-pass filtering device TBPF side in the transmission and reception combiner TRC 2 and TRC 3 constituting the transmitting and receiving combiner, i.e. , addition to the capacitive coupling of each input and output coupling of the common input-output terminal T C and the input-output terminal T R of the reception band-pass filtering device RBPF side, by any of capacitive coupling or magnetic coupling and interstage coupling be coupled to form but the invention may be practiced, the center of each passband of the first to third transmitting and receiving combiner TRC 1 to receive the band-pass device constitute the TRC 3 RBPF and transmitting the band-pass unit TBPF the relationship between each interstage coupling aspect a frequency (resonance frequency), by selecting as described below, the transmission and reception combiner constituted in a smaller size, it is possible to reduce the insertion loss. 即ち、第1ないし第3の送受コンバイナTRC 1ないしTRC 3を構成する帯域通過ろ波器のうち、 That is, first, to the third free handset combiner TRC 1 of the band-pass device constituting the TRC 3,
例えば送信用帯域通過ろ波器TBPFの通過域における中心周波数(共振周波数)が、受信用帯域通過ろ波器RBPFの通過域における中心周波数(共振周波数)より低い場合、送信用帯域通過ろ波器TBPFの段間結合を磁気結合とし、受信用帯域通過ろ波器RBPFの段間結合を容量結合とすると、両帯域通過ろ波器の伝送特性は、図3に示すとおりとなる。 For example the center frequency in the pass band of the transmission band-pass filtering device TBPf (resonance frequency) is lower than the center frequency (resonance frequency) in the pass band of the reception band-pass filtering unit RBPF, transmission band-pass filtering device the interstage coupling TBPF with magnetic coupling, when the capacitive coupling of interstage coupling of the reception band-pass filtering unit RBPF, the transmission characteristics of both the band-pass device is as shown in FIG. 図3において横軸は周波数、縦軸は減衰量、f Lは送信用帯域通過ろ波器TBPFの通過域における中心周波数(共振周波数)、f Hは受信用帯域通過ろ波器RB The horizontal axis represents frequency, and the vertical axis attenuation in FIG 3, f L is the center frequency (resonance frequency) in the pass band of the transmission band-pass filtering unit TBPf, f H is receiving the band-pass unit RB
PFの通過域における中心周波数(共振周波数)で、図から明らかなように、段間結合が容量結合である受信用帯域通過ろ波器RBPFにおいては、共振周波数f Hより低い周波数領域における減衰特性曲線の勾配が急峻で、共振周波数f Hより高い周波数領域における減衰特性曲線の勾配が緩やかであり、段間結合が磁気結合である送信用帯域通過ろ波器TBPFにおいては、共振周波数f Lより高い周波数領域における減衰特性曲線の勾配が急峻で、共振周波数f Lより低い周波数領域における減衰特性曲線の勾配が緩やかである。 At the center frequency (resonance frequency) in the pass band of the PF, as is apparent from the figure, in the reception band-pass filtering device RBPF interstage coupling is a capacitive coupling, the attenuation characteristic in the frequency range lower than the resonance frequency f H slope of the curve is steep, a gentle slope of the attenuation characteristic curve in the frequency region higher than the resonance frequency f H, in the transmission band-pass filtering device TBPF interstage coupling is a magnetic coupling, than the resonance frequency f L a steep slope of the attenuation characteristic curve in the high frequency region is gentle slope of the attenuation characteristic curve in the frequency region lower than the resonance frequency f L. したがって、受信用及び送信用帯域通過ろ波器RBPF及びTBPFの各次数を少なくして、減衰域における減衰量を大にすることができる。 Thus, by reducing the respective order of the reception and transmission band-pass filtering device RBPF and TBPf, the attenuation in the attenuation band can be large. 受信用及び送信用帯域通過ろ波器RBPF及びTBPFを構成する各共振器の負荷Q(Q L )をQ Lk (k=1、2、3、−−−−−、n。n Load Q of each resonator constituting the reception and transmission band-pass filtering device RBPF and TBPF the (Q L) Q Lk (k = 1,2,3, -----, n.n
