Product Description

Sirenza Microdevices’ STA-5063 is a general purpose class A linear amplifier which utilizes InGaP GaAs Heterojunction Bipolar Transistor (HBT) amplifier housed in a low-cost surface-mountable plastic package. This product is specifically designed as a driver amplifier for WLAN 802.11a and 5.8GHz ISM band and 3.3-3.8GHz fixed wireless applications. It can run from a fixed 3.0-3.6V supply with its on chip active bias net work which includes a power up and down control. On-chip

impedance matching circuitry provides a 50Ωnominal RF input and output impedance. Its high linearity makes it an ideal choice for multicarrier and digital applications.
