New amplifier & mixer solutions for backhaul radios to 46.5 GHz

Hittite Microwave Corp. announced the release of two new amplifier and three new mixer products that are ideal for microwave & millimeterwave radios, military sensors, test & measurement equipment and SatCom applications from 24 to 46.5 GHz.

The HMC1040LP3CE is a self-biased GaAs MMIC Low Noise Amplifier (LNA) that operates between 24 and 43.5 GHz and delivers 23 dB gain, 2.2 dB noise figure and output IP3 up to +22 dBm. This versatile LNA consumes only 70 mA from a +2.5V supply while the output P1dB rating of +12 dBm enables it to serve as a LO driver for many of Hittite’s balanced, I/Q and image reject mixers. The HMC1040LP3CE features I/Os that are DC blocked and internally matched to 50 Ohms, and is ideal for high capacity microwave radios and VSAT applications. The HMC1040LP3CE is housed in a compact 3 x 3 mm QFN plastic package.

The HMC1016 is a four stage GaAs PHEMT MMIC Medium Power Amplifier die that operates between 34 and 46.5 GHz. This powerful amplifier provides 22 dB of gain, +26 dBm of saturated output power, and 17% PAE from a +6V supply. With output IP3 as high as +37 dBm, the HMC1016 is an ideal solution for high linearity applications in point-to-point radio, military and space. This compact wideband driver amplifier occupies less than 2 mm2.

The HMC1041LC4 and HMC1042LC4 are compact I/Q MMIC mixers that cover RF frequencies from 17 to 27 GHz and from 15 to 33.5 GHz respectively. Each mixer utilizes two double balanced mixer cells and a 90 degree hybrid, and is fabricated in a GaAs MESFET process. These highly integrated converters can be used as either image reject mixers or as single sideband upconverters with conversion losses as low as 9 dB. The HMC1041LC4 and HMC1042LC4 are housed in footprint compatible 4 x 4 mm QFN packages and require no external components.

The HMC1043LC3 is a special purpose triple balanced mixer that accepts 16 to 22 GHz at the IF port and 26 to 32 GHz at the RF port. The HMC1043LC3 exhibits excellent LO/RF, LO/IF and 2 LO/IF isolation due to optimized balun structures, and requires no external components. The HMC1043LC3 operates with LO drive levels as low as +9 dBm from 7 to 11 GHz, and is ideal for upconversion and downconversion in satellite transponder applications. The HMC1043LC3 is housed in a compact  3 x 3 mm QFN package and requires no external matching components.
