Overview
PRODUCT SUMMARY SKY77703 Power Amplifier Module for CDMA / WCDMA / HSDPA / HSUPA / HSPA+ / LTE – Bands III, IV, IX, X (1710–1785 MHz) Applications • WCDMA handsets • HSDPA • HSUPA • HSPA+ • LTE • CDMA2000 • EVDO Description The SKY77703 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 module packs full 1710–1785 MHz bandwidth coverage into a single compact package.
Because of high efficiencies attained throughout the entire power range, the SKY77703 delivers unsurpassed talk-time advantages.
The SKY77703 meets the stringent spectral linearity requirements of High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term Evolution (LTE) data transmission with high power added efficiency.
A directional coupler is integrated into the module thus eliminating the need for any external coupler.
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 SKY77703 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.
Primary bias to the SKY77703 is supplied directly from any three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output in the 3.
2 to 4.
2 volt range.
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.
