Compact GaN Power Amplifier For Broadband Military & Commercial Applications


Here is a new 70W gallium nitride (GaN) power amplifier that is robust and suits the demands of broadband military and commercial applications 

RFMW has announced design and sales support for a super broadband, GaN solid-state power amplifier (SSPA) from Aethercomm. The SSPA 0.020-6.000-70 operates between 20 MHz to 6.0 GHz and is designed to meet the ramp up in the demand for GaN-based technology for both military and commercial applications.

According to the company, the product is ideal for broadband military platforms as well as commercial applications because it is robust and offers high power over an extremely large bandwidth with decent power added efficiency.

Key features of the new GaN Power Amplifier:

  • The SSPA 0.020-6.000-70 is offered in a modular housing that is approximately 5.5” x 6.5” x 2.0”
  • The weight of this unit is 5.0 pounds maximum.
  • Typical saturated output power of 70 watts at room temperature.
  • Noise figure at room temperature is 10 dB typical.
  • The gain flatness from 20 to 5500 MHz is typically ± 3 dB.
  • Power flatness at saturation is typically ± 3 dB.
  • Input and output VSWR is 2.0:1 typical.
  • Base plate temperature of –20C to +70C.
  • Operates from a +28 Vdc input voltage.
  • The device includes an external DC blanking command that enables and disables the module in 25 uSec maximum.
  • Typical on/off timing values are 18 uSec.
  • A logic low or open circuit disables the amplifier. Logic high will enable the amplifier.
  • Standard features include over/under voltage protection and reverse polarity protection.
  • Input/output RF connectors are SMA female.
  • DC and command voltages are accessible via a DSUB connector.
