Available now from Mimix Broadband is a new gallium arsenide (GaAs) two-stage low-noise gain block amplifier that has a self-biased, single supply design.

Using 0.25um optical etch-stop pseudomorphic high electron mobility transistor (pHEMT) device model technology, this low noise gain block, the CMM1100, covers the 2 to 18GHz frequency bands.

The CMM1100 provides 3.5dB noise figure and 18dB gain, delivering 16dBm P1dB.

This low noise gain block amplifier offers a unique combination of low noise figure and broadband output match by employing a unique feedback stage to provide good noise figure that does not exist in typical distributed low noise designs.

Integrated bias coils and on-chip DC blocking are all inclusive in the compact chip measuring only 1.55 x 1.6 x 0.1mm.

"The use of a broadband feedback topology satisfies the need for low noise figure across the entire 2-18GHz bandwidth", stated Damian McCann, Vice President, Product Development of Mimix Broadband.

"Combined with a distributed output distributed stage, it achieves high gain, high P1dB, and unconditional stability in an industry leading die area".

"This compact, broadband chip offers an easy-to-assemble solution for manufacturers of products and systems for defense EW/ECM, test equipment, microwave radio and Vsat".

Engineering samples are available today from stock.
