Designer Kits

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced four new chip and SMT packaged pHEMT GaAs MMIC Low Noise Amplifiers (LNAs) which are ideal for automotive, broadband, military EW, microwave radio and SatCom applications from 5 to 18 GHz.

The HMC902 and HMC903 are pHEMT GaAs MMIC Low Noise Amplifier chips which are rated from 5 to 10 GHz and 6 to 18 GHz, respectively. These high linearity LNAs deliver up to 20 dB gain and +28 dBm output IP3, with noise figure as low as 1.6 dB. The HMC902 and HMC903 occupy less than 1.5 mm2, feature DC blocked RF I/Os, and are internally matched to 50 Ohms making them ideal for integration into multi-chip-modules (MCMs) and microwave integrated circuits (MICs).

The HMC902LP3E and HMC903LP3E are SMT packaged pHEMT GaAs MMIC Low Noise Amplifiers which are rated from 5 to 10 GHz and 6 to 17 GHz, respectively. These high linearity LNAs deliver up to 19 dB gain and +28 dBm output IP3, with noise figure as low as 1.7 dB. The HMC902LP3E and HMC903LP3E are internally matched to 50 Ohms, are housed in RoHS compliant 3 x 3 mm plastic packages and feature DC blocked RF I/Os.

The HMC902, HMC903, HMC902LP3E and HMC903LP3E LNAs exhibit excellent input and output return losses and deliver output P1dB of up to +16 dBm, making them ideal for high dynamic range receiver applications and for driving the LO port of many of Hittite’s high-level balanced, I/Q and image reject mixers. All four of these self-biased LNAs operate from a single +3.5 V supply consuming between 80 and 90 mA. In addition, the HMC902, HMC903, HMC902LP3E and HMC903LP3E will accept an optional negative gate supply (Vgg) voltage, allowing the designer to tailor the output compression point and DC power consumption of the LNA for each application.

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. Released data sheets are available on-line at www.hittite.com.
