Description
The SKY77192-14 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module
developed for Code Division Multiple Access (CDMA2000) handsets and Wireless Local Loop
applications. This small and efficient module packs full coverage of the 450 ∼ 460 MHz bandwidth
into a single compact package. The SKY77192-14 meets the stringent CDMA2000 linearity
requirements to and exceeding 29 dBm output power.
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 Ω load is realized off-chip within the module package to optimize efficiency and power
performance.
The SKY77192-14 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 SKY77192-14 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 V to 4.2 V 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.
