Omschrijving

The PE1CMO 70cm converter is a multi-purpose converter for receiving the 70 cm band at your 28 MHz HAM receiver.

The local oscillator is a low noise VCO with a small range. The PLL reference is an 1ppm TCXO within 1ppm, 2.5ppm at extended temperature range.
The RF frontend uses SAW filters for a low loss but high performance bandpass filter. The frontend range = 430 - 440MHz .

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.
