Crystal filter 45 mhz circuits
WebFor HF transmitters running on 160 meters (1.8 to 2.0 MHz) or on 80 meters (3.5 to 4.0 MHz), it’s practical to build a VFO for those frequencies. Then you may amplify the VFO signal directly. For example, if you had a crystal controlled QRP designed for 80 meters, an 80 meter VFO could be plugged directly into the crystal socket. WebA crystal filter allows some frequencies to 'pass' through an electrical circuit while attenuating undesired frequencies. An electronic filter can use quartz crystals as resonator components of a filter circuit. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits ( see mechanical filter ).
