ABSTRACT:
A television tuner includes a metal frame having four side plates. The area inside the frame is divided by a shield plate into a first division adjacent to a first side plate and a second division adjacent to a second side plate opposite to the first side plate. A first connector receiving a television signal is disposed on a third side plate forming the first division. The first division contains a first wideband amplifier adjacent to the first connector and a distributor between the first wideband amplifier and a fourth side plate to be adjacent to the first wideband amplifier. A second connector that outputs one of two signal components split in the distributor is disposed on the first side plate. A tuning section is disposed in the second division. Other wideband amplifiers may provide isolation between the distributor, the second connector, and the tuning section.
