SKY65124
High Gain Linear PA Module

The SKY65124 is a fully matched 20-pin, lead-free, surface mount, Multichip Module (MCM) Power Amplifier (PA) designed for WCDMA/PCS/DCS/UTMS/TD-SCDMA radio, repeaters, transmitters, mobile radios and WCS fixed wireless applications operating in the 1930–1990 MHz bandwidth.

All active circuitry in the module is contained in a single Gallium Arsenide (GaAs) Microwave Monolithic integrated Circuit (MMIC).

The device is manufactured with Skyworks Aluminum (Al) GaAs Heterojunction Bipolar Transistor (HBT) process, which allows for single supply operation while maintaining high efficiency and good linearity.

The module can operate over the temperature range of -40 °C to +85 °C. A populated evaluation board is available upon request.
