QPA2735 13 20GHz GaAs Low Noise Amplifier General Description Qorvos QPA2735 is a packaged, high-performance, low noise amplifier fabricated on Qorvos production 90nm pHEMT (QPHT09) process. Covering 13 20 GHz, the QPA2735 provides 25.5 dB small signal gain and P1dB of 18 dBm, while supporting a noise figure of 1.3 dB and IM3 levels of 60 dBc (at Pout=0 dBm/tone). Packaged in a small 4 mm x 4 mm plastic overmold QFN, the QPA2735 is matched to 50 ohms with integrated DC blocking caps on both I/O ports for easy handling and simple system integration. The QPA2735 high performance and ease of handling makes it ideal for satellite and point to point communication systems.
