GaAs pHEMT MMIC Low Noise Amplifier, 0.3 GHz to 20 GHz

The HMC1049 is a GaAs MMIC low noise amplifier (LNA) that operates between 0.3 GHz and 20 GHz. This LNA provides 16 dB of small signal gain, a 1.7 dB noise figure, and an Output IP3 of 27 dBm, requiring only 70 mA from a 7 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. VDD can be applied to Pad 2 with VDD = 7 V or to Pad 4 with VDD = 4 V. Pad 4 requires a bias tee. The HMC1049 is also internally matched to 50 Ω for ease of integration into multichip 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 mil) length.
