50 MHz converter

  
This is a very sensitive 50Mc converter allowing you to receive the entire `Magic Band` (50Mc...52Mc) on your general coverage receiver (28Mc...30Mc). It receives all types of modulated transmissions. It all depends on the receiver used. I`ve tested this project on a allmode Yaesu FRG-100 receiver. Within certain limits you can change the output frequency to suit your needs. The converter is very stable, low nois, sensitive and low on power consumption and can be compared to many commercial 50Mc receivers.

The heart of the converter has been built around Philips SA602 (NE602 or NE612), a twice balanced mixer oscillator. This IC finds his applications in layer capacity communication systems, cellular radio applications, RF data left, VHF-transceivers, broadb
