Microchip introduces first GaN MMIC

23 June 2021

Microchip Technology Inc. has introduced its first gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) designed for satellite communication systems.

Satellites use complex modulation schemes for fast data rates to deliver video and broadband data. This requires systems with high RF output power to ensure the signals retain the desired characteristics.

The GMICP2731-10 GaN MMIC power amplifier works for use in commercial and defense satellite communications, 5G networks and other aerospace and defense systems.

The power amplifier uses GaN-on-silicon carbide (SiC) technology for features including:

  • Up to 10 W of saturated RF output power across 3.5 GHz of bandwidth
  • Power efficiency of 20%
  • 22 dB small-signal gain and 15 dB return loss
  • Integrated DC blocking capacitors
