GaAs MMIC wideband amplifier delivers extremely low phase noise

January 19, 2017 // By Jean-Pierre Joosting
Custom MMIC has added new category to their rapidly expanding standard product offerings – the GaAs MMIC Low Phase Noise Amplifier family, which offers previously unattained phase noise performance.

Phase noise is a critical requirement which defines the performance level of most radars and communications systems. The five product family achieves phase noise performance as low as -165dBc/Hz at 10 kHz offset. They are ideal for use in Local Oscillator (LO) and high sensitivity receiver circuits for military and instrumentation applications.

The MMIC family includes three die and two QFN packaged MMICs covering 6 to 22 and 30 to 40 GHz. Only a single positive power supply of 3- to 5-V is required for these self- biased amplifiers.
