CMD24X ~ ​Low Phase Noise Amplifier Series

Introducing Custom MMIC's new GaAs MMIC Low Phase Noise Amplifier family offers previously unattained phase noise performance.  Phase noise is a critical requirement which defines the performance level of most radars and communications systems as unwanted phase noise leads to loss of target in military radar and can dramatically reduce the effective bit-error-rate (BER) in data links.

The range of GaAs HBT RF and Microwave low phase noise amplifiers (LPNA) MMICs cover 6 to 40GHz ( C-, X-, Ku-, K-, and Ka-band).

The five product family achieves phase noise performance as low as -165dBc/Hz at 10 kHz offset. They are used 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 volts is required for these self- biased amplifiers.
