Highpass / Low pass Diplexer
Bree Engineering model Number 800509 is in a family of elliptic function diplexers optimized for extended 50 ohm match. The lowpass of 0 to 140 MHz and the highpass passband of 160 to 900 MHz both have less than 1.5 dBa of insertion loss. The VSWR is less than 1.5:1.0 from 0 to 900 MHz at the common junction port. Rejection is greater than 40 dBa at 50 MHz from the crossover frequency. Size is 1.5 x 0.5 x 0.3 inches.
