5 GHz to 11 GHz GaAs, pHEMT, MMIC, Low Noise Amplifier

The HMC902 is a gallium arsenide (GaAs), pseudomorphic (pHEMT) monolithic microwave integrated circuit (MMIC), low noise amplifier (LNA), which is self biased with optional bias control for IDQ reduction. The HMC902 operates between 5 GHz and 11 GHz. This LNA provides 20 dB of small signal gain, 1.6 dB noise figure, and output IP3 of 28 dBm, requiring only 80 mA from a 3.5 V supply. The P1dB output power of 16 dBm enables the LNA to function as a local oscillator (LO) driver for balanced, I/Q, or image rejection mixers. The HMC902 also features inputs/outputs that are matched to 50 Ω for ease of integration into multichip modules (MCMs). All data is taken with the HMC902 in a 50 Ω test fixture connected via two 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mil) length.
