MMIC Receivers Span 7 To 28 GHz

Dec. 15, 2006

Some products integrate components to give engineers space-saving advantages. For example, nine gallium-arsenide (GaAs) monolithic-microwave-integrated-circuit (MMIC) receivers integrate low-noise amplifiers (LNAs), I/Q mixers, and local-oscillator (LO) amplifier/multipliers. The devices cover the microwave radio bands from 7 to 28 GHz. The HMC570, HMC571, and HMC572 bare-die products provide a signal-conversion gain of 8 through 10 dB with a noise figure as low as 3 dB. In addition, they provide up to 24 dB of image rejection across their respective frequency bands. The HMC570LC5, HMC571LC5, and HMC572LC5 provide input IP3 values up to +5 dBm. The HMC567LC5, HMC568LC5, and HMC569LC5 provide smallsignal conversion gain to 14 dB with a noise figure as low as 2 dB. They deliver up to 35 dB of image rejection across their respective frequency bands.
