1.98-2.02 GHz High Linearity 4 W Power Amplifier

Skyworks SKY65129-21 is a Microwave Monolithic Integrated Circuit (MMIC) Power Amplifier (PA) with superior output power, linearity, and efficiency. The device is optimized to operate in the 2 GHz frequency band, which makes it ideal for PCS satellite, PCS cellular, and UMTS applications.

The high linearity (high OP1dB and excellent ACLR) and high efficiency of the SKY65129-21 make it ideal for use at the final stage (or close to the final stage) in a transmit chain.

The device is fabricated using Skyworks high reliability Heterojunction Bipolar Transistor (HBT) technology. The device is internally matched and mounted in a 20-pin, 6 x 6 mm Multi-Chip Module (MCM) Surface-Mounted Technology (SMT) package, which allows for a highly manufacturable low cost solution.
