Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has launched two new power amplifier products which are ideal for microwave radio, EW, ECM and radar applications to 28 GHz. Also released is a unique wideband LNA which operates from 300 MHz to 20 GHz and is ideal for wideband multi-chip-module and subsystem applications.

The HMC994LP5E is a GaAs MMIC pHEMT Distributed Power Amplifier which operates between DC and 28 GHz. The amplifier provides 13 dB of gain, +29 dBm of saturated output power, and 23% PAE from a +10V supply. With up to +38 dBm Output IP3, the HMC994LP5Eis ideal for high linearity applications in military and space as well as point-to-point and point-to-multi-point radios. The HMC998LP5Eis a GaAs pHEMT MMIC Distributed Power Amplifier which operates between 100 MHz and 20 GHz. The amplifier provides 11 dB of gain, +41 dBm output IP3, and +31 dBm of output power at 1 dB gain compression while requiring only 500 mA from a +15V supply. The HMC994LP5E and the HMC998LP5Eboth exhibit very flat gain from 4 to 16 GHz and from 3 to 17 GHz respectively, making them ideal for EW, ECM, radar and test equipment applications. Both the HMC994LP5E and the HMC998LP5Eare supplied in leadless QFN 5 x 5 mm surface mount packages and feature I/Os that are internally matched to 50 Ohms.

The HMC1049is a GaAs MMIC pHEMT Low Noise Amplifier die which operates between 300 MHz and 20 GHz and employs a novel topology which maintains an excellent low noise figure of 1.7 dB at low frequencies. The amplifier also delivers 16 dB of small signal gain and output IP3 of +27 dBm, while requiring only 70 mA from a +7 V supply. The P1dB output power of +16 dBm enables the LNA to function as a LO driver for balanced, I/Q or image reject mixers. The HMC1049is internally matched to 50 Ohms for ease of integration into multichip-modules (MCMs).

Die samples, SMT product 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.
