Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced two new GaAs MMIC mixers which are ideal for Point-to-Point and Point-to-Multipoint Radios, VSAT, Telecom, Test Instrumentation, Radar, ECM and Space applications from 6 to 34 GHz. The HMC144LH5 is a Double-Balanced MMIC Mixer which can be used as an upconverter or downconverter from 6 to 20 GHz and requires no external components or DC biasing. Housed in a RoHS compliant ceramic hermetic SMT leadless package, the HMC144LH5 features a wide IF bandwidth of DC to 3 GHz, up to 35 dB of LO/RF isolation and input IP3 of +24 dBm. A highly reliable alternative to hybrid diode mixers, the HMC144LH5 allows the use of surface mount manufacturing techniques and may be upscreened to MIL-PRF-38535 for Class B or Class S applications. The HMC338LC3B is a compact 24 to 34 GHz Sub-Harmonically Pumped (x2) MMIC Mixer with an integrated LO amplifier housed in a leadless RoHS compliant ceramic SMT package. The HMC338LC3B features a wide IF bandwidth of DC to 3 GHz, 2LO to RF isolation of 40 dB, and a LO amplifier with a nominal -5 dBm drive requirement. The RF and LO ports of the HMC338LC3B are DC blocked and matched to 50 Ohms for design convenience, and the device consumes only 30 mA from a +3V supply. The HMC144LH5 and the HMC338LC3B complement Hittite’s line of high performance GaAs Double-Balanced and Sub-Harmonic Mixers which provide broad frequency coverage from 0.6 to 42 GHz. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.
