DATA SHEET SKY77764 Power Amplifier Module for CDMA / WCDMA / HSDPA / HSUPA / HSPA+ / LTE Bands III, IV, IX (1710 MHz1785 MHz) Applications Description WCDMA handsets The SKY77764 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient HSDPA module packs full 1710-1785 MHz bandwidth coverage into a single compact package. Because of HSUPA high efficiencies attained throughout the entire power range, the SKY77764 delivers unsurpassed HSPA+ talk-time advantages. The SKY77764 meets the stringent spectral linearity requirements of High LTE Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term Evolution (LTE) data transmission with high power added efficiency. An integrated directional coupler CDMA2000 eliminates the need for any external coupler. EVDO The Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all amplifier active circuitry, including input and interstage matching circuits. The silicon CMOS support die, Features providing precision biasing for the MMIC affords a true CMOS-compatible control interface. Output match into a 50-ohm load, realized off-chip within the module package, optimizes efficiency and Low voltage positive bias supply 3.0 V to 4.5 V power performance. Good linearity The SKY77764 is manufactured with Skyworks InGaP GaAs Heterojunction Bipolar Transistor (HBT) process which provides for all positive voltage DC supply operation and maintains high efficiency and High efficiency good linearity. While primary bias to the SKY77764 can be supplied directly from any suitable battery - 46% at 28.6 dBm with an output of 3.2 V to 4.2 V, optimal performance is obtained with VCC2 sourced from a DC-DC Large dynamic range power supply adjusted within 0.5 V to 3.6 V based on target output power levels. Power down Small, low profile package executes by setting VENABLE to zero volts. No external supply side switch is needed as typicalof - 3 mm x 3 mm x 0.9 mm leakage is a few microamperes with full primary voltage supplied from the battery. - 10-pad configuration Power down control InGaP Supports low collector voltage operation Digital Enable No VREF required CMOS compatible control signals Integrated Directional Coupler FIGURE 1.
