Chelmsford, MA 07/06/07 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced four new Low Noise Amplifiers (LNAs) which are ideal for applications in Industrial Sensors, Test & Measurement Equipment, Military Radar and Electronic Warfare (EW) applications from 2 to 4 GHz.

The HMC594LC3B is a GaAs pHEMT MMIC LNA which is rated from 2 to 4 GHz, and delivers 10 dB gain, 3 dB noise figure and +36 dBm output IP3. The HMC594LC3B is housed in a 3x3 mm leadless ceramic SMT package, and the RF I/Os are matched to 50 Ohms with no external components.

The HMC609LC4 is a GaAs pHEMT MMIC LNA which is also rated from 2 to 4 GHz, and delivers 20 dB Gain, 3.5 dB noise figure, and +36.5 dBm output IP3. The HMC609LC4 is housed in a 4x4mm leadless ceramic SMT package and the RF I/Os are matched to 50 Ohms with no external components.

The HMC594LC3B and the HMC609LC4 feature excellent gain flatness of ¡À0.2 dB and ¡À0.4 dB respectively, and both deliver consistent linearity across their rated bandwidth. For hybrid and multi-chip module applications, the HMC594LC3B and HMC609LC4 are available in chip form as the HMC594 and the HMC609.

All four of these wide dynamic range LNAs operate from a +6V supply, incorporate DC blocked RF I/Os, and are ideal for use in Industrial Sensors, Fixed Microwave, Test & Measurement Equipment, Military, and Hi-Rel applications.
