摘要： A radio receiver includes a down-converter 110 for receiving a radio multiplexed signal containing a first signal and a second signal, multiplying the first signal and the second signal by a mixer 104 to thereby down-convert the radio multiplexed signal and generate an intermediate frequency signal 5e. The mixer 104 has a control section for controlling an operating bias of the mixer 104 in response to a signal strength of at least either one of the first signal or the second signal. Thus, the dynamic range of the mixer can be widened so that stable image characteristics can be obtained over a wide range of transmission distance.

摘要： An input modulation signal wave 108a is frequency-upconverted to an intermediate frequency signal wave by a frequency mixer 3. By adding a reference signal wave to the intermediate frequency signal wave frequency-upconverted by the frequency mixer 3 by means of a signal combiner 5a, an intermediate frequency multiplex signal wave 7 is generated. The intermediate frequency multiplex signal wave 7 is frequency-upconverted to a milliwave by a second frequency mixer 8. The multiplex signal wave in the milliwave band frequency-upconverted by the second frequency mixer 8 is amplified by a transmission amplifier 10 and transmitted as a radio multiplex signal wave 115 constituted of a radio reference signal wave 106 and a radio signal wave 107 from a transmission antenna 15. With this arrangement, there are provided a microwave band radio transmitter, a microwave band radio receiver and a microwave band radio communication system, which are excellent in controllability of a signal level of a transmission output and able to extend a radio transmission band and a radio transmission distance.

摘要： In conventionally receiving satellite broadcasting (BS, CS) and terrestrial broadcasting (VHF, UHF) services, transmitting the services to a plurality of TV receivers in an individual house results in complicated wiring and a community house is also limited in the number of installed TV receivers due to previously setting a distributor and thus requires an additional distributor to be installed when a TV receiver is additionally installed. The milliwave receiving and transmitting system of the present invention allows a broadcast signal to be transmitted and received indoors via indoor, wireless milliwave transmission without using any indoor wiring.
