Chelmsford, MA — Hittite Microwave Corporation has introduced seven SiGe BiCMOS MMIC mixer RFICs which are ideal for upconversion and downconversion applications in broadband, cellular/3G, WiMAX/4G and fixed wireless systems from 700 MHz to 3.9 GHz.
The HMC684LP4E, HMC685LP4E, HMC688LP4E and HMC666LP4E are SiGe BiCMOS mixer RFICs which are rated from 0.7 to 1.0 GHz, 1.7 to 2.2 GHz, 2.0 to 2.7 GHz and 3.1 to 3.9 GHz, respectively. Each product consists of a high linearity double-balanced mixer core and a matched local oscillator (LO) amplifier which combine to deliver up to +35 dBm input IP3 with only 0 dBm of input LO drive.
The HMC684LP4E, HMC685LP4E, HMC688LP4E and HMC666LP4E feature singled-ended LO and RF ports, while the differential IF ports support intermediate frequencies from DC to 500 MHz. These compact converters are optimized for low side LO frequency plans, and exhibit conversion loss as low as 7 dB with up to 30 dB of LO to RF and LO to IF isolation. They are ideal for upconversion and downconversion applications in GSM, WCDMA, TD-SCDMA, WiBro and WiMAX.
Also released are the HMC686LP4E, HMC687LP4E, and HMC689LP4E SiGe BiCMOS mixer RFICs which are rated from 0.7 to 1.0 GHz, 1.7 to 2.2 GHz, and 2.0 to 2.7 GHz respectively. These three converters are optimized for high side LO applications, and offer similar performance to their low side LO counterparts.
All seven of these BiCMOS MMIC mixers are housed in footprint compatible, RoHS compliant 4x4 mm QFN SMT packages and operate from a single +5V supply. Samples and evaluation PC boards for all SMT packaged products are available.
