Hittite Launches MMIC LNAs With High Linearity and Ultra Flat Gain

Chelmsford, MA -- Hittite Microwave Corporation has introduced four new low-noise amplifiers (LNAs) which are suited for applications in industrial sensors, test and 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 4 x 4 mm leadless ceramic SMT package and the RF I/Os are matched to 50 Ohms with no external components.

The HMC594LC3B and the HMC609LC4 feature a gain flatness of ±0.2 dB and ±0.4 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 and incorporate DC blocked RF I/Os.
