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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

-- New 2W PA & Analog VGA Cover 27.5 to 31 GHz
  
Chelmsford, MA, 11/14/2013 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has announced a new GaAs pHEMT MMIC power amplifier and an analog variable gain amplifier that are ideal for Ka-band VSAT, high capacity microwave radio and radar systems in the 27.5 to 31 GHz frequency range.
 
The HMC7441 is a three-stage GaAs pHEMT Power Amplifier which operates between 27.5 and 31 GHz. The amplifier provides 23 dB of gain and +34 dBm of saturated output power at 25% PAE from a 6 V supply. With an excellent output IP3 of +38 dBm, the HMC7441 power amplifier is ideal for linear applications demanding +34 dBm of efficient saturated output power. The RF I/Os are DC blocked and matched to 50 Ohms for ease of integration into Multi-Chip-Modules (MCMs).HMC7441 is a three-stage GaAs pHEMT Power Amplifier

HMC7441 Functional Diagram The HMC6187LP4E is a GaAs MMIC pHEMT analog variable gain amplifier and/or driver amplifier which operates between 27 and 31.5 GHz and delivers excellent gain flatness. The HMC6187LP4E amplifier provides up to 19 dB of gain, +24 dBm output P1dB, and +31 dBm of output IP3 at maximum gain, while requiring 230 mA from a +5 V supply. A gain control voltage (Vctrl) is provided to allow variable gain control up to 13 dB. The HMC6187LP4E is housed in a RoHS compliant 4 x 4 mm plastic QFN leadless package and is compatible with high volume surface mount manufacturing.

Both products complement Hittite's extensive line of microwave power amplifiers and analog VGAs which provide continuous frequency coverage from 0.01 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 Datasheets are available on-line at www.hittite.com.
