QORVO QPA0007 and QPA0004 electronically reconfigurable dual-band (S- and X-band) GaN power amplifiers (PAs) support a shift in radar architecture for defense, weather and commercial avionics. The patented devices are commercially available and can be rapidly reconfigured for operation between S- and X-bands. This enables a single radar platform to be used across multiple applications, offering precise long-range and short-range capabilities. Devices eliminate the need for independent systems, saving size, weight, power and cost (SWaP-C). Products reduce the BOM and footprint by as much as 50% while improving overall performance. Devices are available in surface mount technology (SMT) packaging and offer improved saturated power (PSAT) and power-added efficiency (PAE) when compared to traditional switched dual-band solutions.
