40m band 7th order Chebychev band pass filter designed as a front end filter to provide image rejection to Receivers from strong out of band signals, provides over over 46dB IF rejection at 9MHz. All filters have been modeled on the PA3AKE Chebychev filter designs, and cover the popular HF amateur bands. Low loss NPO ceramic capacitors have been used along with wire wound high Q inductors to reduce RF losses.
