Analog/Mixed Signal

Family of Bare Die GaAs MMIC Devices Target Aerospace and Industrial Markets

06 June 2017

Microsemi Corp. has introduced a new family of wideband plastic packaged and chip monolithic microwave integrate circuit (MMIC) devices targeted at front-end signal chain applications within the aerospace, defense, and industrial markets.

The new family includes two distributed low noise amplifiers (LNAs) that offer a wide frequency from DC to 27 GHz with higher gain of 17 decibels and OIP3 of 35 dBm. Two other wideband LNAs in the new family provide low noise figure (NF) from 0.5 to 18 GHz with typical NF below 2 dB and no more than 2.5 dB at the band edge.

Two new gallium arsenide (GaAs) switches have improved insertion loss and isolation over a wide frequency range from DC to 20 GHz. These switches require minimal off-chip logic to control system level integration, Microsemi says.

Finally, the wideband PA chip in the new MMIC family maintains flat gain of 17 dB and high OIP3 of 35 dBm from DC to 8 GHz.

The MMIC devices are used in applications such as test and measurement, electronic warfare/electronic countermeasures/electronic counter-countermeasures, high linearity microwave radio, unmanned aerial vehicles (UAV) and other military communications applications.

All of the new MMIC devices are currently sampling.
