Microchip Reveals New GaN MMIC Power Amplifier

Microchip Technology has introduced new GMICP2731-10 GaN MMIC power amplifier that can use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data for Satellite communication systems use.

Microchip The new device, Microchip’s first GaN MMIC, is designed for use in commercial and defense satellite communications, 5G networks and other aerospace and defense systems.

“As communication systems employ complex modulation schemes such as 128-QAM and as the power of solid-state power amplifiers (SSPAs) trends ever upwards, RF power amplifier designers have the difficult challenge of finding higher power solutions while at the same time reducing weight and power consumption,” said Leon Gross, Vice President of Microchip’s Discrete Products Group business unit. “GaN MMICs used in high power SSPAs can achieve greater than 30% lower power and weight as compared to their GaAs counterparts, which is a huge gain for satellite OEMs. This product delivers on the promise of GaN and enables the size, weight, power and cost OEMs are searching for.”

The GMICP2731-10 is fabricated using GaN-on-Silicon Carbide (SiC) technology. It delivers up to 10W of saturated RF output power across the 3.5 GHz of bandwidth between 27.5 to 31 GHz. Its power-added efficiency is 20%, with 22 dB of small-signal gain and 15 dB of return loss.

A balanced architecture allows the GMICP2731-10 to be well matched to 50-ohms and includes integrated DC blocking capacitors at the output to simplify design integration.

Microchip’s GMICP2731-10 complements the company’s existing portfolio of GaAs MMIC RF power amplifiers, switches, low-noise amplifiers, and Wi-Fi front-end modules, as well as a GaN-on-SiC High Electron Mobility Transistor (HEMT) driver and final amplifier transistors for radar systems.

Microchip provides board design support to help with design-ins, as do the company’s distribution partners. The company also provides compact models for the GMICP2731-10, which allow customers to model the performance and expedite the design of the power amplifier in their systems more easily.
