Analog Devices Inc. HMC1126 Low Noise Amplifier

The HMC1126 is a gallium arsenide Pseudomorphic High Electron Mobility Transistor, monolithic microwave integrated circuit (MMIC), distributed power amplifier that operates from 2 GHz to 50 GHz.

The HMC1126 provides 11 dB of gain, 28 dBm output IP3, and 17.5 dBm of output power at 1 dB gain compression, while requiring 65 mA from a 5 V supply. All data is taken with the chip connected via two 1 mil wire bonds of minimal length.

The amplifier inputs and outputs are internally matched to 50 Ω facilitating integration into multichip modules.

The HMC1126 is a cascode distributed power amplifier that uses a fundamental cell of two FETs in series, source to drain. This fundamental cell then duplicates a number of times. The major benefit of this is an increase in the operation bandwidth.

With a small form factor die size, the HMC1126 is ideal in test instrumentation, microwave radios, mil/aero, and fiber optics applications.
