GaN RF transistors offer array of frequency ranges
QPD gallium nitride (GaN) radio frequency (RF) transistors from Qorvo are now in stock at Mouser Electronics. Built on Qorvo's high-performance GaN on silicon carbide (SiC) technology, these high-electron-mobility transistors (HEMTs) with a single-stage matched power amplifier transistor offer a wide array of frequency ranges, output power, and operating voltages for high-efficiency applications.
GaN technology supports RF power densities between five and six times higher than gallium arsenide-based RF amplifiers.
The proven performance and reliability of GaN technology makes it an ideal choice for infrastructure, defense and aerospace applications such as radar, electronic warfare, communications, navigation, and similar applications.
This increase in performance capability offers designers the flexibility to reduce board space and system costs while improving system performance.
The GaN RF transistors available from Mouser Electronics include the recently released QPD1003, the industry's first 500-watt, L-Band power amplifier internally matched to 50Ohms.
It meets the performance needs of high-power phased arrays such as Active Electronic Scanned Array (AESA) radars, which operate in the 1.2 to 1.4GHz frequency range.
These systems require power amplifiers that operate at maximum efficiency resulting in low heat generation in demanding environmental conditions.
