RM805

Power Amplifier Module for Broadband

The RM805 Power Amplifier (PA) is a fully matched 28-pin surface mount module

designed for Private Mobile Radio (PMR), Wireless Local Loop (WLL), and Time

Division Multiple Access/Advanced Mobile Phone Service (TDMA/AMPS) mobile units

operating in the 806-849 MHz cellular bandwidth. Microwave Monolithic Integrated

Circuits (MMICs), comprised of Gallium Arsenide (GaAs) and CMOS, contain all active

circuitry in the module, which includes on-board bias circuitry as well as input and

interstage matching circuits. The output match is realized off-chip within the module

package to optimize efficiency and high power performance (P_{3db_sat}≅ 35.8 dBm)

into a 50 Ω load.

Distinguishing Features

•

Low voltage positive bias supply

Good linearity

High efficiency

Dual mode operation

Large dynamic range

28-pin LCC package

(10 x 13.97 x 1.7 mm)

•

Power down control

This device, manufactured with Skyworks’ GaAs Heterojunction Bipolar Transistor

(HBT) and silicon CMOS processes, provides for all positive voltage DC supply

operation while maintaining high efficiency and good linearity. Primary bias to the

RM805 can be supplied directly from a single cell lithium-ion or other suitable battery

with a nominal output 3.5 Volts.

Applications

•

PMR (806–825 MHz)

TETRA (806–825 MHz)

TDMA (824–849 MHz)

AMPS (824-849 MHz)

Wireless Local Loop

No external supply side switch is needed as typical “off” leakage is a few

microamperes with full primary voltage supplied from the battery.
