Description
M/A-COM’s AM55-0001 is a GaAs power amplifier with
integrated transmit/receive and an antenna diversity switch
in a low cost SSOP 24 plastic package. The AM55-0001
employs active bias circuits that eliminate the need for
external bias adjustment. A ‘Sleep Mode’ is incorporated
which turns off current draw from the positive supply of
the PA during receive mode. The AM55-0001 provides a
10-dB step attenuator for use as a transmit power controller.

The AM55-0001 is designed for low power consumption
and is ideally suited for FSK systems in the 2.4 - 2.5 GHz
bands (North American ISM, Japanese RCR.32 and
European ETSI). Typical applications include WLAN and
wireless portable data collection.
Dimensions are in inches over millemeters.
Ordering Information
This amplifier is also available without diversity switching
(AM55-0007). Either power amplifier can be combined
with a transceiver IC (MD58-0001) to form a complete RF
front end.

The PCB dielectric between RF traces and RF ground
layers should be chosen to reduce RF discontinuities
between 50- Ω lines and package pins. M/A-COM
recommends an FR-4 dielectric thickness of 0.008 in.
(0.2 mm), yielding a 5-0 Ω line width of 0.015 in.
(0.38 mm). The recommended metalization thickness is
1 oz. copper.

Biasing Procedure
The AM55-0001 requires the V bias be applied prior
GG
to any V
bias. Permanent damage may occur if this
DD
procedure is not followed. All FETs in the PA will
draw excessive current and damage internal circuitry.

AM55-0001
The AM55-0001SMB Designer's Kit allows for immediate evaluation of M/A-COM's AM55-0001 integrated Power Amplifier
with T/R and Diversity Switch. The evaluation board consists of an AM55-0001, 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 AM55-0001SMB evaluation PCB and block diagram are illustrated below with all
functional ports labeled.
