The hybrid tuner PCB Board design does not use PIN diodes for band switching. Instead, it uses a very simple three-phase circuit for band switching. The antenna impedance is transformed through a high-inductance coupling circuit to the tuned input circuit. The pre-selected signal is then amplified through Infineon’s high-gain half-bias MOSFET BF5030W. The BG5120K dual MOSFET can be used in two VHF frequency bands.
In the subsequent tuned band-pass filter circuit, channel selection and suppression of excess signals such as adjacent channels and video frequencies are performed. The capacitive image frequency compensation circuit of the preceding tracking trap and band-pass filter is specifically designed to suppress the image frequency.
