Patent ID: 6915529

Claim:
A milliwave transmission device for wirelessly transmitting a milliwave, comprising: a broadcaster-wave receiving circuit receiving a plurality of broadcast waves and converting said plurality of broadcast waves into broadcast signals respectively corresponding to said broadcast waves; and a modulation circuit up-converting said broadcast signal into a milliwave for transmission and reception; a milliwave transmitting circuit transmitting said milliwave such that broadcast signals corresponding to said plurality of broadcast waves are collectively transmitted at one time; and at least one of a first amplifier provided between said broadcast-wave receiving circuit and said modulation circuit for providing a uniform output level of said broadcast signals, a second amplifier provided between said broadcast-wave receiving circuit and said modulation circuit for providing a higher output level of said broadcast signals on a high-frequency side than on a low-frequency side, and a third amplifier provided between said broadcast-wave receiving circuit and said modulation circuit for selectively enhancing among said broadcast waves an output level of a broadcast wave having a required C/N, as compared to another of said broadcast waves.
