Omschrijving

The PE1CMO 23cm converter is a multi-purpose converter for receiving the 23 cm band at your 144 MHz HAM receiver.

The local oscillator is a low noise VCO with a small range. The PLL reference is designed to be connected to an external 10MHz GPS controlled OCXO. The RF frontend uses Helical filter for a low loss but high performance bandpass filter. The frontend can be tuned from 1250 - 1300 MHz .

Dynamic range. The dynamic range is excellent. The mixer is a 17 dBm medium level mixer so that the total output IP3 is around +32 dBm.
