A new family of wideband plastic packaged and chip monolithic microwave integrated circuit (MMIC) devices has been announced by Microsemi. The products add to a growing portfolio of high performance wideband MMICs and include four plastic packaged low noise amplifiers (LNAs), MMA040PP5, MMA041PP5, MMA043PP4 and MMA044PP3; a wideband power amplifier (PA) chip, MMA053AA; and two plastic packaged switches, MMS006PP3 and MMS008PP3.

The new MMIC products will be showcased at the IEEE International Microwave Symposium (IMS2017) 6th to 8th June 2017 in Honolulu, Hawaii as a part of Microwave Week 2017.

The new packaged amplifiers include two new distributed LNAs (MMA040PP5 and MMA041PP5) which perform over a frequency from DC to 27GHz with gain of 17dB and OIP3 of 35dBm. They are packaged in a small 5mm plastic QFN package suitable for size constrained applications. Two additional wideband LNAs (MMA043PP4 and MMA044PP3) provide low noise figure (NF) from 0.5-18GHz with typical NF below 2dB and no more than 2.5dB at the band edge.

Two new wideband GaAs switches (MMS006PP3 and MMS008PPS) have improved insertion loss and isolation over a wider frequency range from DC to 20Ghz when compared to competitive parts. These are housed in 3mm plastic QFN packages which are useful for high performance requirements in constrained size applications. The devices require minimal off-chip logic to control simplifying system level integration.

A wideband PA chip (MMA053AA) was also released which maintains flat gain of 17dB and high OIP3 of 35dBm from DC to 8GHz, which Microsemi claims to exceed the performance of competitive parts. Customers can leverage all these devices’ leading performance capabilities to meet demanding system and module line-up requirements with minimal DC power consumption.

“Our new product introductions represent Microsemi's significant investment in enhancing our MMIC product portfolio as we continue to address our customers' overall requirements,” said Kevin Harrington, Director of strategic marketing for Microsemi’s RF/Microwave Discrete Products business unit. “We are committed to being a long-term trusted supplier of superior performance MMIC products for our customers as we continue to invest and expand leading-edge MMIC devices.”

Microsemi’s new MMIC wideband LNA, distributed wideband MMIC power amplifier and wideband MMIC switches are suitable for a number of front-end signal chain applications within the aerospace, defense and industrial markets, including test and measurement, electronic warfare (EW)/electronic countermeasures/electronic counter-countermeasures, high linearity microwave radio, and unmanned aerial vehicle (UAV) and other military communications applications. Global market research and consulting company Strategy Analytics estimates that GaAs MMICs sold into the EW, radar and microwave communications markets will reach $500m by 2019.
