Agilent Technologies Debuts High Linearity Enhancement-mode PHEMT FET

4/3/2003 - Agilent Technologies Inc. (NYSE: A) announced a high linearity E-pHEMT (enhancement-mode pseudomorphic high electron mobility transistor) field effect transistor (FET) designed for low noise, high dynamic range operation in cost-sensitive wireless infrastructure applications that operate between 450 MHz and 6 GHz.

At 3V, 30 mA and 2 GHz, the single voltage Agilent ATF-58143 E-pHEMT FET features 0.5 dB noise figure with +16.5 dB associated gain, combined with +30.5 dBm third-order output intercept point (OIP3) and +16.5 dBm linear output power (1 dB gain compression). It's ideal for the first and second stage of front-end LNAs (low-noise amplifiers) in cellular/PCS/WCDMA base station, wireless local loop, fixed wireless access and other high-performance applications that operate between 450 MHz and 6 GHz. The ATF-58143 delivers high linearity of 30.5 dBm OIP3 at low power consumption of only 30 mA at 3V, which reduces heat generation in today's compact equipment designs. Single-voltage operation also eliminates the need for voltage inverter circuitry or dual-voltage voltage supplies.

Agilent remains the industry's only supplier of E-pHEMT devices that feature single-voltage operation, which greatly simplifies voltage supply design. The single 3V supply voltage makes this new Agilent E-pHEMT FET the logical choice to replace single-voltage HBT (heterojunction bipolar transistor), and dual-voltage conventional PHEMT and GaAs HFET (heterostructure FET) devices.

The ATF-58143 E-pHEMT FET is housed in the miniature 2.0 x 2.1 mm SOT-343 package.

U.S. Pricing and Availability
The Agilent ATF-58143 is priced at $1.08 at 10,000 - 24,999 piece quantities and is immediately 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
