GaN power amplifier targets 17.3 to 21.2 GHz band

Mouser Electronics is now stocking the QPA1724 Ku/K-Band gallium nitride (GaN) power amplifier (PA) from Qorvo.

Qorvo says that the device delivers twice the power of similar PAs, and offers excellent wideband linear power, gain and power added efficiency.

This high-power MIMIC amplifier targets the 17.3 to 21.2 GHz SATCOM (Ku-K) band.

It delivers a saturated output power of 20 W (~43 dBm) with a small signal gain of 25 dB and power-added efficiency (PAE) of 27%.

Fabricated using Qorvo’s production 0.15 μm GaN-on-SiC process (QGaN15), the device includes on-chip blocking capacitors following the DC grounds on the input and output ports. The QPA1724 PA is also fully matched to 50 ohms with DC grounded I/O ports for peak ESD performance to simplify system integration.  

Ideally suited for commercial and military radar and satellite communication (SATCOM) applications, including low-earth-orbit constellations and wide bandwidth, multi-carrier high-data throughput solutions, the QPA1724 is available in a 7.5 mm × 6.0 mm × 1.6 mm QFN package and 100% DC and RF tested to ensure compliance with electrical specifications.

For evaluation and development, the QPA1724EVB evaluation board is available to order from Mouser.
