PRODUCT SUMMARY SKY77198-12 Power Amplifier Module for TD-SCDMA (1880–1920 MHz, 2010-2025 MHz) Applications Description • TD-SCDMA handsets The SKY77198-12 Power Amplifier Module (PAM) is a fully matched, 10-pad, surface mount module developed for Time Division Synchronous Code Division Multiple Access (TD-SCDMA) applications. Skyworks’ SKY77198-12 also supports TD-SCDMA multi-slot operation. Features • Low voltage positive bias supply - 3.2 V to 4.2 V • Supports low collector voltage operation • Good linearity • High efficiency - 39% @ 28 dBm • Large dynamic range • Small, low profile package - 3 mm x 3 mm 0.85 mm - 10-pad configuration • Power-down control • Low power-state control This small and efficient module packs full 1880–1920 MHz and 2010-2025 MHz bandwidth coverage into a single compact package. The PAM meets the stringent spectral linearity requirements of TD-SCDMA transmission, with high power added efficiency for power output of up to 28 dBm. A single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module such as on-board bias circuit and input and interstage matching circuits. Output match is realized off-chip within the module package to optimize efficiency and power performance into a 50 Ω load. The SKY77198-12 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. 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. • InGaP • CMOS Compatible Control • Integrated Directional Coupler MODULE VEN (5) MMIC VMODE_0 (4) Driver Stage Bias Power Stage Bias VMODE_1 (3) VCC2 (10) VCC1 (1) RF_IN (2) Input Match DA Inter-Stage Match PA Output Match (9) RF_OUT GND (7, 8) CPL (6) 201005_001 Figure 1.
