SKY65171-21 1930 – 2170 MHz, 0.5 W Power Amplifier
SKYWORKS SKY65171-21 is a fully-matched, 0.5 W Power Amplifier (PA) with high efficiency, designed for use in the 1930 to 2170 MHz band. The device is fabricated using SKYWORKS high reliability Indium Gallium Phosphide (InGaP) Heterojunction Bipolar Transistor (HBT) technology. This process allows for single supply operation while maintaining high efficiency and good linearity. The SKY65171-21 contains all of the active bias and RF matching circuits, which make it easy to integrate into 50 Ω RF systems. The internal input and output match are optimized for gain, 1 dB Compression Point (P1dB), Adjacent Channel Power Ratio (ACPR), Adjacent Channel Leakage Ratio (ACLR),and efficiency when integrated in a 50 Ω system. The primary bias to the SKY65171-21 can be supplied directly from a single 5 VDC supply. The PA is designed to operate with lower current by reducing the bias voltage.
