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 (P3db_sat ≅ 35.8 dBm)
into a 50 Ω load.
Distinguishing Features

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.

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.

Package and Handling Information
Power Amplifier Module for Broadband
Package and Handling Information
Because of its sensitivity to moisture absorption, this device package is baked and vacuum packed
prior to shipment. Instructions on the shipping container label must be followed regarding exposure
to moisture after the container seal is broken, otherwise, problems related to moisture absorption
may occur when the part is subjected to high temperature during solder assembly.
The RM805 is capable of withstanding an MSL 3/225 °C solder reflow. Care must be taken when
attaching this product, whether it is done manually or in a production solder reflow environment. If
the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 °C per second;
maximum temperature should not exceed 225 °C. If the part is manually attached, precaution
should be taken to insure that the part is not subjected to temperatures exceeding 225 °C for more
than 10 seconds. For details on both attachment techniques, precautions, and handling procedures
recommended by Skyworks, please refer to Application Note: PCB Design and SMT
Assembly/Rework, Document Number 101752. Additional information on standard SMT reflow profiles
can also be found in the JEDEC Standard J–STD–020A.
Production quantities of this product are shipped in the standard tape-and-reel format. For
packaging details, refer to Application Note: Tape and Reel, Document Number 101568.

Electrostatic Discharge Sensitivity
RM805
Power Amplifier Module for Broadband
Electrostatic Discharge Sensitivity
The RM805 is a Class I device. Figure 5 lists the Electrostatic Discharge (ESD) immunity level for
each pin of the RM805 product. The numbers in Figure 5 specify the ESD threshold level for each
pin where the I-V curve between the pin and ground starts to show degradation. The ESD testing
was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body Model.
Since 2000 volts represents the maximum measurement limit of the test equipment used, pins
marked > 2000 V pass 2000V ESD stress.

Various failure criteria can be utilized when performing ESD testing. Many vendors employ
relaxed ESD failure standards which fail devices only after “the pin fails the electrical specification
limits” or “the pin becomes completely non-functional”. Skyworks employs most stringent criteria,
fails devices as soon as the pin begins to show any degradation on a curve tracer.
To avoid ESD damage, both latent and visible, it is very important that the product assembly and
test areas follow the Class-1 ESD handling precautions listed in Table 5.
