PURPOSE:To obtain the maximum ability of amplifiers at all times, by inputting signals having (n+1) types of frequencies while switching it to 2<n> sets of power amplifiers, and obtaining the amplified outputs of each frequency from (n+1) sets of output terminals while switching the outputs. CONSTITUTION:For example, in case of n=2, signals in (n+1) types of frequencies f0-fn are applied to input terminals 1-4 of 2<n> sets of power amplifiers 5-8 with the time slot as shown in figure. A signal f0 is inputted to the terminals 1-4 at time slot t0, it is inputted to the terminals 1-2 at t1, f1 is 3-4, and f0 is to the terminals 1-2, f1 is to 3 and f2 is to 4 at time slot t2, respectively. Change-over devices 9-12, 16, 17 are switched depending on the time slots t0-t2 and connected to synthesizers 13-15 and filters 18-20. This switching is made so that the amplified outputs f0-f2 can be obtained to output terminals 21-23 in the output time slots as shown in figure. |
