Hittite Microwave Corp., the world class supplier of complete MMIC based solutions for communication & military markets, has launched a new power amplifier which maintains excellent performance over its operating frequency range. The new amplifier, HMC6981LS6, is ideal for high linearity point-to-point and point-to-multi-point radios, SATCOM, military and space applications.

The HMC6981LS6 is a four-stage GaAs PHEMT MMIC power amplifier which operates between 15 to 20 GHz.  Ideal for covering the 18 GHz licensed microwave radio band, the amplifier provides 26 dB of gain, +34.5 dBm  of saturated output power, and 25% PAE from a +6 V supply. With up to +43.5 dBm OIP3 and drawing only 1100 mA  from a +6 V supply, the HMC6981LS6 is also ideal for “green” mode of operation which require amplifiers offering increased RF output performance for less DC input power.

The HMC6981LS6 is housed in a ceramic RoHS compliant 6 x 6 mm QFN leadless air cavity package which exhibits low thermal resistance and is compatible with surface mount manufacturing techniques. The RF I/Os are internally matched to 50 Ohms.

The HMC6981LS6 complements Hittite’s extensive line of power amplifiers which provide frequency coverage for all of the licensed microwave radio bands from 6 to 86 GHz. Samples 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
