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 designed to be connected to an external 10MHz GPS controlled OCXO. The RF frontend uses SMD double SAW filters for good supression of unwanted signals. The dynamic range is excellent. The mixer is a 17 dBm medium level mixer so that the total output IP3 is around +32 dBm.
