Agilent Unveils Field Effect Transistor with Highest Linearity E-pHEMT

8/1/2003 - Agilent Technologies Inc. (NYSE: A) introduced its highest linearity E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) field effect transistor (FET) in a new lower thermal resistance version of the miniature 2 mm x 2 mm 8-pin leadless plastic chip carrier (LPCC) package.

The Agilent ATF-501P8 single-voltage E-pHEMT is optimized for use in transmitter power amplifiers and receiver low-noise amplifiers used in cellular/PCS/WCDMA base stations, low-earth-orbit satellite systems, terrestrial multichannel multipoint distribution systems (MMDSs), wireless local area networks (WLANs), wireless local loop (WLL), fixed wireless access, and other services operating in the 50 MHz to 6 GHz frequency range.

At 2 GHz, the single voltage operation Agilent ATF-501P8 provides +45.5 dBm third-order output intercept point (OIP3), resulting in a more efficient multi-channel amplifier capable of handling a greater number of voice and data channels. Its low thermal resistance of only 23 C/W (compared to 33 C/W for similar devices in the conventional LPCC package) enables the Agilent ATF-501P8 to dissipate nearly 2 W at +85( C ambient temperature while maintaining a chip temperature that assures high reliability. The ATF-501P8 also features +29 dBm linear output power (P1dB), 15 dB gain and 65 percent power-added efficiency at 2 GHz, combined with a low 1.0 dB noise figure. Its compact size of 2 mm x 2 mm saves valuable printed circuit board space.

Agilent remains the industry's only supplier of E-pHEMT devices that feature single-voltage operation. With single-voltage operation, high-power efficiency and superior RF performance, Agilent's E-pHEMT devices are the logical choice to replace both single-voltage HBTs, with their higher noise figures, and dual-voltage conventional PHEMT and GaAs HFET (heterostructure FET) devices.

U.S. Pricing and Availability
The Agilent ATF-501P8 is priced at $3.13 each in 5,000 to 9,999-piece quantities and available through Agilent's direct sales channel and through Agilent's worldwide distribution partners. Further information on Agilent's RF semiconductor products is available at www.agilent.com/view/rf.
