Custom MMIC reveals GaAs low noise amplifier

The gallium arsenide amplifier operates from 33 to 45 GHz and is suited tor point-to-point and point-to-multipoint radios
Custom MMIC, a developer of monolithic microwave integrated circuits (MMICs) has added the CMD190 to its MMIC library of standard products.

The CMD190 is an efficient GaAs MMIC ultra low noise amplifier for applications from 33 to 45 GHz. This amplifier delivers over 19 dB of gain with a corresponding noise figure of 2.1 dB at 36 GHz.


The CMD190 has an all-positive bias design, and eliminates the complicated and costly negative bias sequencing circuits while also simplifying board layout.

What's more, the use of an on-chip pinch-off tracking circuit ensures consistent performance over temperature and process variation.

The CMD190 is a 50 Ω matched design, which eliminates the need for external DC blocks and RF port matching. It offers full passivation for increased reliability and moisture protection.
