Power Amplifier Module for CDMA

CX77144 PAM, designed for cellular handsets utilizing CDMA and WLL, packs a full 887–925 MHz bandwidth coverage into a single compact package. It meets stringent IS95 CDMA2000 linearity requirements to and exceeding 27.5 dBm output power. A low current digital pin (VCONT) provides improved efficiency for low RF power range. A single GaAs MMIC contains all active circuitry, on-board bias circuitry, input and interstage matching circuits. Skyworks’ GaAs HBT process provides for all positive voltage DC supply operation with high efficiency and good linearity. See Data Sheet below for more details.

Please note: CX77144-15 is being discontinued and is not recommended for new design.
