January 17, 2011

HMC4x4 mm SMT LNAs for Microwave Radio, Military & Space, VSAT, Test & Sensors. Three New LNAs Support High Dynamic Range Applications from 2 to 28 GHz.

Hittite Microwave Corp., the world class supplier of complete MMIC based solutions for communication & military markets, has introduced three new SMT packaged GaAs pHEMT/HEMT MMIC low noise amplifiers (LNAs) which are ideal for microwave radio, VSAT, military & space, sensors and test instrumentation applications from 2 to 28 GHz.

The HMC751LC4 , HMC752LC4 and the HMC772LC4 are GaAs pHEMT/HEMT MMIC Low Noise Amplifiers which are rated from 17 to 27 GHz, 24 to 28 GHz, and from 2 to 12 GHz respectively. These LNAs also feature high dynamic range and excellent input and output return losses, making them ideal for high capacity microwave radio, VSAT and other demanding applications from 2 to 28 GHz. The HMC751LC4 , HMC752LC4 and the HMC772LC4 have been designed to provide noise figure as low as 1.8 dB with up to 25 dB of gain, and +26 dBm output IP3 from a single supply of +3/+4V. These LNAs are also capable of supplying up to +13 dBm P1 dB output power, which enables them to function as LO drivers for Hittite’s wide range of balanced, I/Q or image reject mixers.

The HMC751LC4 , HMC752LC4 and the HMC772LC4 are housed in RoHS compliant 4x4 mm ceramic SMT packages, feature I/Os that are DC blocked and internally matched to 50 Ohms, and are ideal for integration into Multi-Chip-Modules (MCMs).

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.
