QPA2237数据手册Qorvo中文资料规格书

描述 Description

Qorvo's QPA2237 is a wideband amplifier fabricated on Qorvo's production 0.25um GaN on SiC process. The QPA2237 operates from 0.03 – 2.5 GHz and provides greater than 10W of saturated output power with greater than 13 dB of large signal gain and greater than 48% power-added efficiency.
The QPA2237 is available in a low-cost, surface-mount, 20 lead, 4x4 OVM QFN. It is ideally suited to support both radar and communication applications across defense and commercial markets as well as electronic warfare. The QPA2237 is fully matched to 50 ohm at both RF ports allowing for simple system integration. DC blocks are required on both RF ports and the drain voltage must be injected through an off chip bias-tee on the RF output port.
Lead-free and RoHS compliant.
Evaluation boards are available upon request.
For additional information on GaN thermal performance refer to the following application note and video.
