08 · Up / Down Converter
Features
- 01
Built for QO-100 — Good for QO-100 , the first geostationary satellite with a HamRadio transponder. - 02 Configurable local oscillator — Default 1968MHz for 70cm IF signal, configurable by the customer from 1050MHz to 2700MHz in 1kHz step. Local Oscillator TK stability 2.5ppm (-30°…+75°C); for even more stability, an external 10MHz input is available.
- 03 Two IF input versions — check before ordering
— -15dBm and +20dBm IF version (please check your version before using it). Version 1 for multi-mode SSB CW FM ATV D-ATV , with input around -15dBm. Version 2 for SSB CW FM, with input around +20dBm (attenuator on PCB included). Please note the version you would like to buy. - 04
Rx/ — For the Rx <---> Tx switch, please use the IF signal.Tx switching - 05 HPA2225 — companion 13cm band high gain PA — Amplification of signals with all types of modulation. Very suitable for transmitters with very low RF transmission output power (under 1mW output), such as Adalm Pluto or similar. The output port is protected by a circulator.
