New package cuts FET thermal resistance

Agilent Technologies has put its highest linearity E-pHEMT field effect transistor in a new lower-thermal-resistance version of the miniature 2 x 2mm 8-pin leadless plastic chip carrier package.

Agilent Technologies has put its highest linearity E-pHEMT field effect transistor in a new lower-thermal-resistance version of the miniature 2 x 2mm 8-pin leadless plastic chip carrier (LPCC) package.

The Agilent ATF-501P8 single-voltage E-pHEMT is optimised for use in transmitter power amplifiers and receiver low-noise amplifiers used in cellular/PCS/WCDMA basestations, 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 50MHz to 6GHz frequency range.

At 2GHz, the single voltage operation Agilent ATF-501P8 provides +45.5dBm third-order output intercept point (OIP3), resulting in a more efficient multichannel amplifier capable of handling a greater number of voice and data channels.

Its low thermal resistance of only 23C/W (compared with 33C/W for similar devices in the conventional LPCC package) enables the Agilent ATF-501P8 to dissipate nearly 2W at +85C ambient temperature while maintaining a chip temperature that assures high reliability.

The ATF-501P8 also features +29dBm linear output power (P1dB), 15dB gain and 65% power-added efficiency at 2GHz, combined with a low 1.0dB noise figure.

Its compact size of 2 x 2mm 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.

The Agilent ATF-501P8 is available now through Agilent's direct sales channel and through Agilent's worldwide distribution partners.
