Product Description
RFMD’s SXB4089Z amplifier is a high efficiency InGaP/GaAs heterojunc-
tion bipolar transistor (HBT) MMIC housed in low-cost, surface-mountable
plastic package. These amplifiers are specially designed for use as driver
devices for infrastructure equipment in the 400MHz to 2500MHz cellular,
ISM, WLL, PCS, WCDMA applications. Its high linearity makes it an ideal
choice for multi-carrier as well as digital applications.
