Hittite Microwave Corporation introduces its integrated, High IP3 Dual Downconverter RFIC, which is designed for use in wireless infrastructure applications from 800 to 960 MHz, including those based on CDMA, WCDMA, GSM, GPRS and EDGE standards. The HMC581LP6(E) is comprised of two identical downconverter channels including high IP3 mixers and LO and IF amplifiers. It features high input IP3 of +26 dBm, high conversion gain of 9.5 dB and low SSB noise figure of 13 dB. The passive mixer outputs and IF amplifier inputs are positioned so that an external IF filter can be placed in series between them. The single LO input requires 0 dBm of LO drive, allowing both channels of the converter to be driven directly from a single synthesizer output.
