DATA SHEET CX77107 PA Module for CDMA / PCS (1850–1910 MHz) Applications • Personal Communications Services (PCS) • Wireless local loop (WLL) Features • Low voltage positive 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 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. 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 Ω 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 three-cell Ni-Cd, a single-cell Li-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. • Full U.S. PCS coverage Figure 1.

This amplifier was selected by characterizing a group of devices and choosing a part with average electrical performance for both nominal and the full range of recommended operating conditions, including worst case limits. The graphs illustrate the digital signal characteristics of the CX77107. Shown are power sweep characteristics for key performance parameters over temperature and frequency, up to 28.5 dBm output power. The data was taken up to and including 16 dBm output power with the bias mode control pin setting of VCONT = 2.5 volts. Beyond 16 dBm output power, the VCONT was set to zero volts. Figure 2.

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. Figure 15 Typical Case Markings (Top View) The CX77107 is capable of withstanding an MSL3/240 °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 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 Skyworks 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–020. Production quantities of this product are shipped in the standard tape-and-reel format.

The CX77107 is a Class I device. Figure 17 lists the Electrostatic Discharge (ESD) immunity level for each non-ground pin of the CX77107 product. The numbers in Figure 17 specify the ESD threshold level for each non-ground pin where the I-V curve between the pin and ground starts to show degradation. The ESD testing was performed in compliance with MIL-STD883E Method 3015.7 using the Human Body Model. If ESD damage threshold magnitude is found to consistently exceed 2000 volts on a given pin, this so is indicated. If ESD damage threshold below 2000 volts is measured for either polarity, numbers are indicated that represent worst case values observed in product characterization. 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.
