路に与える影響を貌明するための図である。In the same figure, the input terminals of the transmitting side duplexers BPTII and BPT12 are the transmitting *TX-11. The output terminals are connected to the respective transmitting circuits via the respective circulators housed in the TX-12, and the output terminals are connected to the respective circulators T-11 and T-12.
-12 is connected to the antenna of 1.Therefore, the transmitters TX-11, TX-12..., the transmitter side splitter BPT-11, BPT-12... and receivers RX-11, RX-12..., receiving side duplexer BPR-
If all the panels 11...-, BPR-12... are mounted in a wireless device, the input/output terminals of the duplexer can have their respective predetermined electrical characteristics changed. However, for example when replacing a transmitter or receiver, or when using this panel for inspection.
When the link U1 is disconnected, the device side terminal of the corresponding transmitting side duplexer BPT-11 is opened, and the instantaneous characteristics of this duplexer change drastically. FIG. 3 is a diagram for clarifying the influence on the transmission path when the device side terminal of the device is open (-).

れる。In the figure, when the transmitter TX-21 connected to the duplexer BPT-21 is disconnected, the load impedance of this duplexer becomes infinite, so the transmitter The impedance viewed from the side changes, and the characteristics of the duplexer BPT-21 also change. On the other hand, the output of the transmitter which has passed through the duplexer BPT-22 is sent to the circulator T-22 and T as shown by the arrow.

The BPT-32 and the transmitters TX-31 and TX-32 are connected via the circulator housed in the transmitter am as in Fig. 1.When the U link U3 is disconnected, the transmitter &'TX-32 The effect on the output wave is exactly the same as above.

と言う問題があった。The influence of such deterioration in transmission characteristics on the amount of information to be transmitted has not been considered a problem in the case of analog information. However, when transmitting digital information using multi-level phase modulation waves such as 8-phase and 16-phase phase shift)-keying waves or 16-level orthogonal amplitude modulation waves, the transmission standards are very strict. There is a problem in that such transmission distortion cannot be ignored.
