Chelmsford, MA, 1/31/2011 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has introduced a new SMT packaged wideband Voltage Variable Attenuator (VVA) and a new SMT wideband analog Variable Gain Amplifier (VGA). These new high linearity products are ideal for broadband, cellular/3G, WiMAX/4G and military EW applications from 400 MHz to 6 GHz.

The HMC973LP3E is an absorptive VVA, which operates from 0.5 to 6 GHz and is ideal for applications which require a continuously variable attenuation setting. The HMC973LP3E accepts a single analog control signal between 0 and +5V, and provides up to 26 dB of attenuation range. This high range VVA features a monolithic shunt-type topology which is non-reflective and well matched at all control voltage settings; furthermore, unlike other GaAs FET based VVAs, the HMC973LP3E exhibits excellent linearity of +35 dBm input IP3 throughout its control range. The HMC973LP3E is housed in a RoHS compliant 3 x 3 mm QFN leadless plastic package, and requires no external matching components.

HMC972LP5E analog controlled VGAHMC972LP5E block diagramAlso released is the HMC972LP5E analog controlled VGA, which is comprised of two high linearity VVAs and a high linearity amplifier. This wide range analog VGA operates from 0.5 to 6 GHz, and can be set to provide between 35 dB of attenuation, and 15 dB of gain. The HMC972LP5E accepts a single control voltage between 0 and +5V, to achieve up to 50 dB of gain/attenuation variation. This high linearity analog VGA also delivers noise figure of only 7.5 dB in its maximum gain state, and exhibits a high output IP3 of up to +28 dBm. The HMC972LP5E is housed in a RoHS compliant 5 x 5 mm QFN leadless plastic package, and requires no external matching components.

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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
