|This is a Smith Chart of a 20 meter bandpass filter that I built as part of a homebrew transceiver. This filter has a passband that ranges from about 13.7 to 15.4 MHz. It is swept here from 13 to 16 Mhz in 50 kHz steps. The Smith Chart shows that the filter presents a reasonably good approximation to a 50 ohm load for the 20m transmitter output. It is also well matched at 15 MHz for WWV reception.|
