QPA2237 0.03 2.5GHz 10W GaN Power Amplifier Product Description Qorvos QPA2237 is a wideband amplifier fabricated on Qorvos production 0.25um GaN on SiC process. The QPA2237 operates from 0.03 2.5 GHz and provides 10W of saturated output power with 13 dB of large signal gain and 52% power-added efficiency. The QPA2237 is available in a low-cost, surface-mount, 20 QFN 4x4 mm 20L 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 Product Features QPA2237 is fully matched to 50 boatth RF ports allowing for simple system integration. DC blocks are required on Frequency Range: 0.03 2.5 GHz both RF ports and the drain voltage must be injected P : 40 dBm at PIN = 27 dBm SAT through an off chip bias-tee on the RF output port. PAE: 52% Large Signal Gain: 13 dB Lead-free and RoHS compliant. Small Signal Gain: 18.5 dB Input Return Loss: 9 dB Output Return Loss: 9.5 dB Bias: V = 32 V, I = 360 mA D DQ Wideband Flat Power Package Dimensions: 4.0 x 4.0 x 0.85 mm Performance is typical across frequency.
