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 sur-
face-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 50Ω nominal RF input
and output impedance. Its high linearity makes it an ideal
choice for multicarrier and digital applications. Housed in an
industry standard SOT-363 package, it has no blind solder
joints and designed for low cost.
