SMT Mixer

Hittite Microwave has introduced a new HMC258LC3B GaAs MMIC sub-harmonic SMT mixer intended for microwave radios, VSAT, test and measurement, instrumentation and military applications from 14.5 to 19.5 GHz. The unit has an integrated LO amplifier housed in a 3 x 3 mm leadless RoHS-compliant ceramic SMT package. The HMC258LC3B features a wide IF bandwidth of DC to 3.5 GHz, and high 2LO-to-RF isolation of 45 dB that eliminates the need for additional filtering. The HMC258LC3B features a LO amplifier with a nominal 0 dBm drive requirement and requires no external matching components, making it ideal for integrated subsystem applications. The RF and LO ports of the HMC258LC3B are DC blocked and matched to 50 Ω for design convenience, and the device consumes only 42 mA from a +5 V supply.

WiFi Front-end Module

TriQuint Semiconductor is shipping a new Model SCM6M7010 dual-band WiFi front-end module (FEM) for wireless RF chip manufacturing, covering the 2.4 to 5.0 GHz frequency bands in the WiFi portion of RF solutions. TriQuint’s new front-end module enables a size reduction and enhanced performance because all critical device functions are built into a single chip. By utilizing three modules in parallel within the RF front end, three receive and transmit “3 x 3” signal paths are available instead of one, enabling significantly higher data rates.

MMIC Receiver

Mimix Broadband has introduced its XR1011-QH GaAs monolithic microwave integrated circuit (MMIC) receiver that covers the 4.5 to 10.5 GHz frequency bands. The highly integrated receiver has a noise figure of 1.8 dB and 13 dB conversion gain across the band. The receiver integrates an image reject mixer, an LO buffer amplifier and a low noise amplifier within a fully molded 4 x 4 mm QFN package that is RoHS-compliant. The image reject mixer eliminates the need for an image bandpass filter after the amplifier to remove thermal noise at the image frequency. The XR1011-QH is well suited for wireless communications applications such as millimeter-wave point-to-point radio, local multipoint distribution services (LMDS), SATCOM and VSAT.
