New Sub-Harmonic Mixer Covers 14.5 to 19.5 GHz Microwave Radio Band
Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a new GaAs MMIC Sub-Harmonic SMT mixer which is ideal for Microwave Radios, VSAT, Test & Measurement, Instrumentation, and Military applications from 14.5 to 19.5 GHz. The HMC258LC3B is a compact 14.5 to 19.5 GHz Sub-Harmonically Pumped (x2) MMIC Mixer with an integrated LO amplifier housed in a 3x3 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, which 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 Ohms for design convenience, and the device consumes only 42 mA from a +5V supply. The HMC258LC3B complements Hittite’s line of high performance GaAs Double-Balanced and Sub-Harmonic Mixers which provide broad frequency coverage from 450 MHz 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.
