PRODUCT SUMMARY SKY77195 Dual-Band PA Module for WCDMA / HSDPA Band I (1920–1980 MHz) and Band VIII (880–915 MHz) APPLICATIONS • WCDMA handsets • HSDPA Features • Low voltage positive bias supply: 3.2 V to 4.2 V The SKY77195 Power Amplifier Module (PAM) is a fully matched, 14-pad, surface mount module developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient module packs full WCDMA Band I and Band VIII coverage into a single compact package. The SKY77195 meets the stringent spectral linearity requirements of WCDMA transmission, with high power added efficiency for power output to 27.5 dBm (Band I) and 28 dBm (Band VIII). The SKY77195 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA) data transmission with high power added efficiency. A directional coupler is integrated into the module thus eliminating the need for any external coupler. • Good linearity • High efficiency - 40% @ 27.5 dBm • Large dynamic range • 14-pad package - 5 mm x 4 mm x 0.85 mm • Power down control • InGaP • Supports low collector voltage 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. Output match into a 50-ohm load is realized off-chip within the module package to optimize efficiency and power performance. The SKY77195 PAM is manufactured with Skyworks’ InGaP GaAs Heterojunction Bipolar Transistor (HBT) BiFET process that provides for all positive voltage DC supply operation while maintaining high efficiency and good linearity. No VREF voltage is required. Power down is accomplished by setting the voltage on VENABLE 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. • Digital Enable • No VREF required • CMOS compatible control signals • Integrated Directional Coupler Figure 1.
