Custom RF Diplexer

RF Diplexer


This Bree Engineering RF diplexer exhibits low insertion loss, high return loss, and high rejection across the specific frequencies on both channels. The Diplexer contains a high pass from common to Channel 2 with a Lowpass from common to Channel 1. The combined response allows for consistent Return Loss to be greater than 17 dB across the lowpass passband. The high pass passband extends out to 14 GHz with some trade-offs in return loss and insertion loss as the filter increases into the higher frequencies above 6 GHz. The response of the RF Diplexer allows for low insertion loss to be less than 0.5 dBa below 6 GHz and less than 1.0 dBa from 6 GHz to 14 GHz. This Diplexer can also sustain rejection to be greater than 40 dBc through the entire diplexer, while being greater than 50 and 60 dBc at certain frequency ranges.
