HMC1049 GaAs MMIC Low-Noise Amplifier

Analog Devices' HMC1049 is a GaAs MMIC low-noise amplifier which operates between 0.3 and 20 GHz. This LNA provides 16 dB of small signal gain, 1.7 dB noise figure, and output IP3 of 27 dBm, while requiring only 70 mA from a 7 V supply. The P1dB output power of 16 dBm enables the LNA to function as a LO driver for balanced, I/Q or image reject mixers. VDD can be applied to pad 2 or pad 4. Pad 4 will require a bias tee. The HMC1049 also is internally matched to 50 Ω for ease of integration into multi-chip-modules (MCMs). All data is taken with the chip in a 50 Ω test fixture connected via 0.025 mm (1 mil) diameter wire bonds of 0.31 mm (12 mils) length.
