Triquints Model TAT8804D1H

Power Doubler Drives CATV Applications

Nov. 19, 2013
A MMIC device boosts broadband power levels in CATV infrastructure equipment.

Model TAT8804D1H is a linear GaAs monolithic-microwave-integrated-circuit (MMIC) power doubler developed by TriQuint Semiconductor for cable-television (CATV) infrastructure applications requiring flat gain and low distortion. The push-pull cascade design, nominally designed for 50 to 1000 MHz, provides 21-dB typical gain and +34-dBm output power at 1200 MHz. It includes RF electrostatic-discharge (ESD) protection and variable bias control and typically draws 650 mA current from a +12-VDC supply. A good fit for CATV line amplifiers and head-end equipment, it is supplied in a 40-pin, 5 x 7 mm QFN package.
