DATA SHEET SKY77768 Power Amplifier Module for WCDMA / HSDPA / HSUPA / HSPA+ / LTE Band VIII (880 MHz915 MHz) Applications Description WCDMA handsets The SKY77768 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 880-915 MHz bandwidth coverage into a single compact package. Because of high HSUPA efficiencies attained throughout the entire power range, the SKY77768 delivers unsurpassed talk-time HSPA+ advantages. The SKY77768 meets the stringent spectral linearity requirements of High Speed LTE 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 eliminates the need for any external coupler. Features The Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all amplifier Low voltage positive bias active circuitry, including input and interstage matching circuits. The silicon CMOS support die, supply 3.2 V to 4.2 V providing precision biasing for the MMIC affords a true CMOS-compatible control interface. Output Good linearity match into a 50-ohm load, realized off-chip within the module package, optimizes efficiency and High efficiency power performance. - 50% at 28.5 dBm The SKY77768 is manufactured with Skyworks InGaP GaAs Heterojunction Bipolar Transistor (HBT) Large dynamic range process which provides for all positive voltage DC supply operation and maintains high efficiency and good linearity. While primary bias to the SKY77768 can be supplied directly from any suitable battery Small, low profile package - 3 mm x 3 mm x 0.9 mm with an output of 3.2 V to 4.2 V, optimal performance is obtained with VCC2 sourced from a DCDC power supply adjusted within 0.5 V to 3.6 V based on target output power levels. Power down - 10-pad configuration executes by setting VENABLE to zero volts. No external supply side switch is needed as typicalof Power down control leakage is a few microamperes with full primary voltage supplied from the battery. InGaP Supports low collector voltage operation Digital Enable No VREF required CMOS compatible control signals Integrated Directional Coupler FIGURE 1.
