Function and Explanation
IF output pins of VHF-UHF band
functions.
Higher output power can be obtained
by connecting registor (ex. 470
) to
the ground.
Power supply for VHF-UHF band
functions.
VHF and UHF MIX output pin.
These pins should be equipped with
tank circuit to adjust frequency.
VRF signal input pin from antenna.
Bypass pin for VHF MIX input.
Grounded through capacitor.
GND pin of MIX, IF amplifier and
regulator.
Bypass pin for UHF MIX input.
Grounded through capacitor.
URF signal input pin from antenna.
