Description
M/A-COM‘s AM55-0004 power amplifier/switch integrates
a power amplifier and transmit/receive switch in a low cost
SSOP package. The power amplifier delivers +24 dBm of
linear power with high efficiency and can be operated at
supply voltages as low as 2.7 V. It is ideally suited for
QPSK or other linearly modulated systems in the 1.8 to 2.0
GHz frequency band. The power amplifier/switch is fully
monolithic and requires only one output capacitor for
power match. The T/R switch achieves good insertion loss
and isolation without degrading the overall linearity. The
AM55-0004 is ideally suited for final stage power
amplification in linear TDD systems. The integrated switch
is convenient for duplexing. The AM55-0004 can also be
used as a driver stage for high power systems. Typical
applications include Japanese PHS systems or PCN/PCS
transmit chains. M/A-COM‘s AM55-0004 is fabricated
using a mature 0.5-micron gate length GaAs process. The
process features full passivation for increased
performance and reliability.

Recommended PCB Configuration
The PCB dielectric between RF traces and RF
ground layers should be chosen to reduce RF
discontinuities between 50-ú lines and package
pins. M/A-COM recommends an FR-4 dielectric
thickness of 0.008 in. (0.2 mm), yielding a 50-ú line
width of 0.015 in. (0.38 mm). The recommended
metalization thickness is 1 oz. copper. Shaded
traces are vias to DC routing layer and traces on
DC routing layer.

Biasing Procedure
The AM55-0004 requires that VGG bias be applied
prior to any VDD bias. Permanent damage may
occur if this procedure is not followed. All FETs in
the PA will draw excessive current and damage
internal circuitry.

Designer‘s Kit (AM55-0004SMB)
The AM55-0004SMB Designer's Kit allows for immediate evaluation of M/A-COM's AM55-0004 integrated Power
Amplifier and T/R Switch. The evaluation board consists of an AM55-0004, recommended external surface
mount circuitry, RF connectors and a DC multipin connector, all mounted to a multi-layer FR-4 PCB. Other items
included in the Designer's Kit: a floppy disk (with typical performance data and a .DXF file of the recommended
PCB layout) and any additional Application Notes. The AM55-0004SMB PA/Switch evaluation PCB and block

AM55-0004SMB Biasing Procedure
In order to prevent transients which may damage the MMIC, please adhere to the following procedure.
• Turn on all power supplies and set all voltages to 0 volts BEFORE connecting the power supplies to the
DC connector.
• Apply -4.0 volt supply or GND to DC connector pin 9 (VSW , see truth table for desired mode).
• Apply -4.0 volt supply or GND to DC connector pin 13 (VSW , see truth table for desired mode).
• Apply a -4.0 volt supply to the DC connector pin 16 (VG1).
• Apply a -4.0 volt supply to the DC connector pin 18 (VG2).
• Apply a +4.8 volt supply to the DC connector pin 2 (VDD1).
• Apply a +4.8 volt supply to the DC connector pin 20 (VDD2).
• Apply GND to DC connector pin 5 (Save Tx).
• Adjust VG1 supply for desired VDD1 quiescent current (typically 30 mA).
• Adjust VG2 supply for desired VDD2 quiescent current (typically 65 mA).
• Change voltage on DC connector pin 5 as required (Save Tx, see truth table for desired mode).
• Apply RF power and test.
• To power off, reverse above procedure
1. Set VG1 & VG2 to -4 V.
2. Set VDD1 & VDD2 to 0 V.
3. Set control voltage supplies to 0 V.
4. Disconnect bias lines from DC connector.
5. Turn off power supplies.
