Diplexer

The diplexer allows sharing of a common antenna, while providing isolation between the high power transmitter and the sensitive receiver input. The diplexer used in this system is a no tune design and only requires adherence to standard RF practices to achieve good performance. NOTE: Original diplexer design and P-SPICE simulation by Steve, KC7ZVT.
