DATA SHEET CX77107: PA Module for CDMA / PCS (1850–1910 MHz) The CX77107 Power Amplifier Module (PAM) is a fully matched 10-pin surface mount module developed for Personal Communications Service (PCS) and Wireless Local Loop (WLL) applications. This small and efficient Power Amplifier packs full 1850–1910 MHz bandwidth coverage into a single compact package. The CX77107 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 low current (VCONT) pin is provided to improve efficiency for the low RF power range of operation. APPLICATIONS • Personal Communications Services (PCS) • Wireless local loop (WLL) DISTINGUISHING FEATU FEATURES RES The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC contains on-board bias circuitry, as well as input and interstage matching circuits. The output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 W load. This device is manufactured with Skyworks’ GaAs Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. Primary bias to the CX77107 is supplied directly from a threecell nickel cadmium, a single-cell lithium ion, or other suitable battery with an output in the 3 to 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. • Low voltage positive bias supply • • • • • • • • • (3.2 V to 4.2 V) Good linearity High efficiency Large dynamic range 10-pin package 4 mm x 4 mm x 1.5 mm Power down control Low power-state control InGaP IS95/CDMA2000 Full U.S. PCS coverage VREF (5) VCC1 (1) Driver Stage Bias RF IN (2) Input Match VCONT (4) VCC2 (10) Power Stage Bias DA Inter Stage Match PA Output Match (8) RF OUT MMIC MODULE (3, 6, 7, 9) GND (3, 6, 7, 9) GND 101782_001 Figure 1.

PPin 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 CX77107 is capable of withstanding an MSL 3/240 °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 12 JULY 3, 2003 should not exceed 240 °C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 240 °C for more than 10 seconds. For details on both attachment techniques, precautions, and handling procedures recommended by Skyworks, 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–020B. Production quantities of this product are shipped in the standard tape-and-reel format.

ESD Sensitivity Areas (Top View) Various failure criteria can be utilized when performing ESD testing. Many vendors employ relaxed ESD failure standards which fail devices only after “the pin fails the electrical specification limits” or “the pin becomes completely nonfunctional”. Skyworks employs most stringent criteria; fails devices as soon as the pin begins to show any degradation on a curve tracer. To avoid ESD damage, both latent and visible, it is very important that the product assembly and test areas follow the Class-1 ESD handling precautions listed in Table 7. Table 7.
