Abstract :
An all solid state 13 GHz link for transmission of 32 and 120 channel PCM signals has been developed at NERA AS, Division Bergen. The latest developments in solid state design has been utilized in the design. The transmitter power is generated by a phase locked 2 GHz microstrip oscillator followed by a microstrip broadband multiplier. The receiver local oscillator is a 2 GHz phase locked cavity oscillator. The local oscillator multiplier is integrated with the balanced mixer on a common alumina substrate. 2 -PSK modulation with coherent demodulation is employed. The digital signals are regenerated before transmission and after demodulation.
