The QPB0220J is a solid state driver amplifier based on GaN MMIC technology, with an operating range of 2 – 18 GHz with a saturated output power of 39 - 42 dBm (8 - 16 Watts). Its compact size and weight allow it to be used to drive a number of Spatium power amplifiers in microwave high power transmitters for EW and radar applications.

Planar multistage driver module for use with existing Spatium platforms operating in the 2 – 18 GHz frequency band. A variable attenuator in conjunction with a temperature sensor compensates for variation in gain over the operating temperature range. Gate bias and variable attenuator settings are digitally programmable using non-volatile I2C digital potentiometers. RF input and output are via SMA connectors. DC and control interface is provided via a Micro D-Sub connector.
