Abstract
In this paper, design and implementation of frequency down converter based on LC filter technic. Single frequency down converter, designed a low-noise amplifier, mixer, IF amplifier, LC filter was configured. And it is composed of DC block capacitors and RF bypass capacitor. LC filter, replace it with the IC reduced the power and realized low cost. The gain of single down converter is about 10dBm and realized by 18MHz bandwidth at 70MHz band.
