Description
M/A-COM's AM55-0003 is a GaAs power amplifier with integrated transmit/receive and an antenna diversity switch in a low cost SSOP 28 plastic package. The power amplifier delivers +24 dBm of linear power with high efficiency and can be operated with voltages as low as 2.7 volts. The power amplifier switch is fully monolithic. The T/R and diversity switches achieve good insertion loss and isolation without degrading the overall linearity. The switches can be controlled with CMOS logic levels. The AM55-0003 is ideally suited for QPSK, BPSK or other linearly modulated systems in the 2.4 GHz ISM frequency band. It can also be used in GFSK systems where levels of +25 dBm are required. Typical applications include WLAN and wireless portable data collection. This power amplifier can be combined with a transceiver IC (MD58-0001 or MD58-0002) to form a complete RF front end. M/A-COM's AM55-0003 is fabricated using a mature 0.5-micron gate length GaAs process. The process features full passivation for increased performance and reliability.

The PCB dielectric between RF traces and RF ground layers should be chosen to reduce RF discontinuities between 50- lines and package pins. M/A-COM recommends an FR-4 dielectric thickness of 0.008 in. (0.2 mm), yielding a 50- 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 AM55-0003 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 (AM55-0003SMB)
The AM55-0003SMB Designer's Kit allows for immediate evaluation of M/A-COM's AM55-0003 integrated power amplifier with T/R and diversity switches. The evaluation board consists of an AM55-0003, recommended external surface mount circuitry, RF connectors and a DC multi-pin 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 AM55-0003SMB evaluation PCB and block diagram are illustrated below with all functional ports labeled.

250 mW Power Amplifier with T/R and Diversity Switches AM55-0003SMB Biasing Procedure
In order to prevent transients which may damage the MMIC, please adhere to the following procedure. q Turn on all power supplies and set all voltages to 0 volts BEFORE connecting the power supplies to the DC connector. q Apply a -5.0 volt supply to DC connector pin 10 (V ). G1 q Apply a -5.0 volt supply to DC connector pin 6 (V ). G2 q Apply a -5.0 volt supply to DC connector pin 12 (V ). G3 q Apply a +5.0 volt supply to the DC connector pin 20 (V DD TR, VDD ANT). q Apply a +5.0 volt supply to the DC connector pin 8 (V DD1). q Apply a +5.0 volt supply to the DC connector pin 14 (V DD2). q Apply a +5.0 volt supply to the DC connector pin 16 (V DD3). q Apply a GND or +5.0 volt supply to the DC connector pin 18 (T/R CTRL, see truth table for desired mode). q Apply a GND or +5.0 volt supply to the DC connector pin 2 (ANT CTRL, see truth table for desired mode). q Adjust V G1, VG2, VG3 supplies to -5 volts. q Adjust all V DD supplies to +5 volts. q Adjust V G1 supply for desired VDD1 quiescent current (typically 20 mA, VG1 nominally -2.5 volts). q Adjust V G2 supply for desired VDD2 quiescent current (typically 70 mA, VG2 nominally -2.5 volts). q Adjust V G3 supply for desired VDD3 quiescent current (typically 90 mA, VG3 nominally -2.5 volts). q To power off, reverse above procedure. 1) Set all VDD lines to 0 volts. 2) Set VG1, VG2 and VG3 to 0 volts. 3) Disconnect bias lines from DC connector. 4) Turn off power supplies.
