つ努力をしても逆効果になることがある。The configuration of a conventional repeater consisting of a switch matrix and a corresponding transmitter/receiver is shown in FIG. 1. In FIG. 1, 11, 12, and 13 are receivers that have 100% backup equipment, and three typical examples of how to connect the working equipment and the backup equipment are shown. 11 is an example using a switch, 1
2 is an example using a synthesizer, and 13 is an example using a 3 dB hybrid. 21, 22, and 23 are transmitters that have 100% backup equipment, and there are three types of connection methods between the active equipment and the standby equipment, as in the case of the receiver. 101 is an N×N switch matrix in which connections between the number N of input terminals and the number N of output terminals can be arbitrarily set. Typical configurations for the switch matrix include N 1:N distributors, N:1 combiners, and N2
It consists of 5 switch elements. However, FIG. 1 only shows the connection relationship between the distributor 1 combiner and the switches for three circuits. The characteristics of these circuits are described below with emphasis on circuit loss and reliability. First, the loss L of the switch matrix
Assuming that the loss in the switch section is S and the loss in the distributor and combiner is Lc, respectively (as the direction of loss increase with a positive sign), Lsm = S +2Lc (da) (11 where
Lc = 10101o (da) (2JNext, looking at the connection method of the receiver output section and transmitter input section, 11 and 2
With the connection using the switch shown in 1, the loss is small and can be ignored, but from the point of view of reliability, it is necessary to
It has the disadvantage of being inferior to dB hybrid. On the other hand 12,
13. Connections using the 3 dB hybrid combiner shown in 21 and 22 are highly reliable, but the loss is 3 dB at each connection.
There is a disadvantage of being a B student. In particular, when adding an amplifier to reduce the total input/output loss of 6 dB, the reliability of the entire circuit decreases by the reliability of this amplifier, making it more reliable than a combiner or /h hybrid. Even if you try to maintain your sexuality, it may have the opposite effect.

い。The present invention overcomes the drawbacks of these conventional construction methods and provides a switch matrix and repeater with low loss and high reliability. FIG. 2 shows an example of the configuration of a repeater according to the present invention. 11...2・N is 100%
The iol transmitter with spare units has 224 switch matrices (1o1', 102') each with N input and output terminals.
, 103' and 104') (input and output terminals are each 2N), 3dB for connecting between 31chi matrices.
N on both the receiver side and the transmitter side.
No. 1 N bullet is required. ix2 switch fist matrix (
8M) is the NXN switch matrix (SM) in Figure 1.
The same idea as the composition of can be applied to the composition of representatives. Let's now consider the loss in the circuit shown in Figure 2. First, the loss L of the 2x2 switch Φ matrix
sm' is Lsm' = 8, where S is the loss of the switch part and Lc' is the loss of the splitter 2 combiner.
+ 2 * Lc' (ds) ' (3J where L
c' = 10101o/2=101ogN-a(as
) +4) Compared with the loss of equations (1) and (2) in the conventional configuration, Lsm'=8+2Lc-6=Lsm-6(ds) +s
In other words, the circuit structure has 6dB less loss than the conventional one.
Becomes □. The loss L7 from the receiver output for active or backup use to the transmitter input each includes 3 dB hybrid, so it increases by 0 dB and becomes L? = Lsm' + 6 = -Lsm. This is equivalent to the loss of a single conventional NXN switch matrix. Therefore, the switch 9 combiner or 3 dB hybrid included in the receiver and transmitter in the conventional example is no longer necessary, which improves loss and reliability, reduces manufacturing cost, reduces weight, etc. The effects of the present invention are significant.
