Reconfigurable Driver Amplifier enables Next-Gen Dual-Band Radar

The Qorvo QPA0004 dual-band GaN MMIC power amplifier enables next generation S and X-band radar systems

RFMW announces design and sales support for a dual-band GaN MMIC amplifier from Qorvo. The QPA0004 power amplifier enables next generation radar systems with reconfigurable RF output delivering 9 Watts of Psat RF power in S-band (3.1 to 3.5 GHz) and 8 Watts in X-band (9 to 11 GHz). Large signal gain is 21 dB (S-band) and 19.0 dB (X-band) from the 7 x 4 mm SMT device operating from a 26 volt bias. Test results show that a dual, S/X-band implementation of the QPA0004 has better performance than individual S and X-band MMICs combined with a SPST switch, a significant advantage in SWaP-C design considerations.
