SKY65126-21

800-900 MHz High Linearity 2 W Power Amplifier


Please note: SKY65126-21 is being discontinued and is not recommended for new designs.

The SKY65126-21 is a fully matched 20-pin, lead-free, surface mount, Multichip Module (MCM) Power Amplifier (PA) designed for WCDMA/CDMA/TDMA/GSM/LTE radio, repeaters, transmitters, mobile radios and Femto cell base station applications operating in the 800–900 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.
