GaAs MMIC wideband amps show very low phase noise

January 19, 2017 // By Graham Prophet
Custom MMIC (Chelmsford, Massachusetts) has added a GaAs MMIC low phase noise amplifier family offering phase noise performance that the company characterises as previously unattainable. The five-product family achieves phase noise performance as low as -165dBc/Hz at 10 kHz offset.

Use the parts 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 5V is required for these self-biased amplifiers.
