Micro-Duplexer


A good duplexer can make the difference between hearing AO-27 full quieting and hearing a bunch of muffled static. The main purpose of a duplexer is to separate the transmit and receive signals

2m/70cm Diplexer
The easiest way to set the filters up without a network analyser, is to connect a good 50 Ohm load to the antenna port and adjust the spacing between the turns of the coils to achieve a good VSWR

2m - 70cm diplexer
With this diplexer, you can connect a 2m (144-146 MHz) and 70cm (430-440 MHz) transmitter to a single dualband antenna, or a dualband transmitter to two seperate antennas

2m-70cm Duplexers-Diplexer
Onze 2 m band eindigt bij 146 MHz en de 70 cm band begint bij 430 MHz. Het midden ligt op 146 + 430 - 2 = 288 MHz

33 MHz diplexer
This is optional, but the diplexer should be mounted as close to the mixer's IF output as possible
