Product Details

The HMC903 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. This LNA provides 19 dB of small signal gain, 1.6 dB noise figure, and an output third-order intercept (IP3) of 27 dBm, 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 HMC903 also features inputs/outputs that are dc blocked and internally matched to 50 Ω for ease of integration into multichip modules (MCMs). All data is taken with the HMC903 in a 50 Ω test fixture connected via 0.025 mm (1 mil) diameter with bonds of 0.31 mm (12 mil) length.

Tools & Simulations


Sys-Parameter Models for Keysight Genesys

Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.


Design Tools


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
