RM914
Power Amplifier Module for AMPS Applications (824–849 MHz)
The RM914 Advanced Mobile Phone Service (AMPS) Power Amplifier is a fully
matched 6-pin surface mount module designed for mobile units operating in the
824-849 MHz cellular bandwidth. This device can be driven to power output levels
beyond 31 dBm for high efficiency FM mode operation. A single 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. The output match is realized off-chip and within the module package to
optimize efficiency and power performance into a 50 Ω load. This device is
manufactured with Skyworks’s GaAs HBT process that provides for all positive
voltage DC supply operation while maintaining high efficiency. Primary bias to the
RM914 can be supplied directly from a three cell nickel-cadmium, single cell
www.DataSheelith4iUum.c-oiomn, or other suitable battery with output in the 3-4 volt range. Power down is
accomplished by setting the voltage on the low current reference pin 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.
Distinguishing Features
• Low voltage positive bias supply
(3 to 4 Volts, typical)
• High efficiency
• Large dynamic range
• 6-pin package
(6mm x 6mm x 1.5 mm)
• Power down control
Applications
• Analog cellular (AMPS)
• Wireless local loop (WLL)

Package Dimensions and Pin Descriptions
Package Dimensions and Pin Descriptions
The RM914 is a multi-layer laminate base, overmold encapsulated modular package designed for
surface mount solder attachment to a printed circuit board. Figure 12 is a mechanical drawing of
the pad layout for this package and Figure 13 illustrates typical case markings. The pin numbering
convention starts with pin 1 in the upper left, as indicated in Figure 12, and increments
counter-clockwise around the package. Table 5 describes each pin function.
