1.8 to 54 MHz Low Pass Filter
A transmitter low pass filter design project was started with goals of low insertion loss, broad SWR
LC band pass filter circuit
Design considerations, circuit and formulas for a constant-k LC band pass filter for RF applications
A 50MHz High Pass TVI Filter
For problems of TVI a three-stage high-pass filter that blocks low-frequency 50MHz signals while letting through UHF TV
Junk Box NDB Low Pass Filter
Canadian beacons either have just a carrier no offsetor are tuned using the USB with about a 400 Hertz offset
