BOEBLINGEN, Germany -- Agilent Technologies today announced two additional members of its family of high-linearity E-pHEMT (enhancement-mode pseudomorphic high-electron-mobility transistor) FETs (field effecttransistors) in the industry-standard 4.5 mm x 4.1 mm x 1.5 mm SOT-89 surface-mount package. By using an industry-standard package, Agilent's newATF-52189 and ATF-53189 and previously introduced ATF-50189 single-voltage E-pHEMT FETs simplify upgrading 50 MHz to 6 GHz base stations to higher-channel capacity.

The ATF-52189 and ATF-53189, from Agilent's Semiconductor Products Group, are designed for use in the transmitter power amplifiers and receiver low-noise amplifiers in cellular and PCS base stations, low-earth-orbit satellite systems, terrestrial multichannel multipoint distribution systems(MMDSs) and other communications applications operating from 450 MHz to 6 GHz.

The 42 dBm third-order output intercept point (OIP3) at 2 GHz of theATF-52189 results in an efficient amplifier capable of handling a large number of voice and data channels. At 2 GHz, its other specifications include typical 27 dBm linear output power (P1dB), 16 dB gain and 55-percent power-added efficiency (PAE), combined with a 1.5 dB noise figure. Typical operating bias is 4.5 V at 200 mA. It is particularly well-suited for use as a medium-power, high-linearity transmitter driver or pre-driver amplifier.

The ATF-53189 features an even lower 0.85 dB noise figure, combined with a 40 dBm OIP3, 23 dBm P1dB, 15.5 dB gain and 46-percent PAE. Typical operating bias is 4.0 V at 135 mA. This makes it an excellent choice as a low-noise high-linearity amplifier for receiver front-end stages or as a medium-power, high-linearity transmitter driver or pre-driver amplifier.

The ATF-52189 and ATF-53189 are based on the E-pHEMT process, which features excellent performance uniformity and a point mean-time-to-failure (MTTF) of greater than 300 years. These devices are supplied in lead-free packaging with a moisture sensitivity level-1 (MSL1) rating.
