Chelmsford, MA — Hittite Microwave Corporation has introduced three 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 LNAs 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 LNAs 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/+4 V. These LNAs are also capable of supplying up to +13 dBm P1 dB output power, which enables them to function as LO drivers for the company"s wide range of balanced, I/Q or image reject mixers.

The devices 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 are available.
