The ADH903S is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), low noise amplifier (LNA), which is self-biased with the optional bias control for IDQ reduction. It operates between 6 GHz and 18 GHz (Die) and 6 GHz to 17 GHz (LH5 Pkg). This LNA provides 19 dB of small signal gain, 1.6 dB noise figure, and an output third-order intercept (IP3) of 27 dBm (Die only), requiring only 90 mA of supply current from a 3.5 V supply. The output power for a 1 dB compression (P1dB) of 16 dBm enables the LNA to function as a local oscillator (LO) driver for balanced, I/Q, or image rejection mixers. The ADH903S also features inputs/outputs that are dc blocked and internally matched to 50 Ω for ease of integration into multichip modules (MCMs).
