Description
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.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
