Mechanical UHF tuner with LC tuning stage PCB

摘要

The UHF tuner with lamdax1/4 type LC resonant circuit comprises a LC resonant unit (30) of a mixer integrated with a first resonant line, a first stator plate, and an IF coil on a PCB, and a LC resonant unit (40) of a RF input circuit integrated with a second resonant line, and a second stator plate or a PCB. Each LC resonant unit is placed beside each varicon plate (13).
