A fully integrated gallium-arsenide (GaAs), monolithic-microwave-integrated- circuit (MMIC) receiver has been spawned for wirelesscommunications applications like millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), satcom, and very small aperture terminal (VSAT). The XR1011-QH covers the 4.5- to-10.5-GHz frequency bands. It flaunts a noise figure of 1.8 dB and 13 dB conversion gain across the band. The receiver integrates an image-reject mixer, a local-oscillator (LO) buffer amplifier, and a low-noise amplifier (LNA) within a RoHScompliant, 4 X 4-mm QFN package. The image-reject mixer eliminates the need for an image bandpass filter after the amplifier. P&A: sampling. Production quantities will be available in 12 to 14 weeks.
