Preliminary Information This document contains information on a new product. The parametric information, although not fully characterized, is the result of testing initial devices. CX77133 Power Amplifier Module for CDMA PCS (1850-1910 MHz) The CX77133 Power Amplifier Module (PAM) is a fully matched, 6-pin surface mount module developed for Personal Communications Service (PCS) and wireless local loop applications. This small and efficient Power Amplifier packs a full 1850-1910 MHz bandwidth coverage into a single compact package. The CX77133 meets the stringent spectral linearity requirements of Code Division Multiple Access (CDMA) PCS transmission with high power added efficiency for power output of up to 28 dBm. A single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all the active circuitry in the module. The MMIC contains on-board bias circuitry, as well as input and interstage matching circuits. Output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 load. This device is manufactured with Skyworks' GaAs Heterojunction Bipolar Transistor (HBT) process, which provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the CX77133 is supplied directly from a three-cell nickel cadmium, a single-cell lithium ion, or other suitable battery with an output in the 3-4 volt range. Power down is accomplished by setting the voltage on the low current reference pin to zero volts. No external supply side switch is needed as typical "off" leakage is a few microamperes with full primary voltage supplied from the battery.

Skyworks Preliminary Information 101537P6 March 27, 2002 CX77133 Package and Handling Information Power Amplifier Module for CDMA PCS (1850-1910 MHz) Package and Handling Information Because of its sensitivity to moisture absorption, this device package is baked and vacuum packed prior to shipment. Instructions on the shipping container label must be followed regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The CX77133 is capable of withstanding an MSL 3/225 C solder reflow. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 C per second; maximum temperature should not exceed 225 C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 225 C for more than 10 seconds. For details on both attachment techniques, precautions, and handling procedures recommended by Conexant, please refer to Application Note: PCB Design and SMT Assembly/Rework, Document Number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD-020A. Production quantities of this product are shipped in the standard tape-and-reel format.
