Functional Block Diagram
Description
M/A-COM’s MAAMSS0045 is a high dynamic range,
GaAs MMIC, low noise amplifier in a lead-free
SOIC 8-lead, surface mount, plastic package. It
employs external input matching to obtain optimum
noise figure performance and operating frequency
flexibility. The MAAMSS0045 also features flexible
biasing to control the current consumption vs.
dynamic range trade-off. The MAAMSS0045 can
operate from any positive supply voltage in the 3 V
to 8 V range. Its current can be controlled over a
range of 20 mA to 60 mA with an external resistor.
The MAAMSS0045 is ideally suited for use where
low noise figure, high gain, high dynamic range, and
low power consumption are required.
Typical
applications included receiver front ends in PDC,
DCS-1800, DCS-1900 and other PCN/PCS base
stations. It is also useful as a gain block, buffer,
driver, and IF amplifier in both fixed or portable PDC
and PCN/PCS systems.
The MAAMSS0045 is fabricated using a low-cost
0.5-micron gate length GaAs process. The process
features full passivation for increased performance
and reliability. The MAAMSS0045 is 100% RF
tested to ensure performance specification
compliance.

Recommended PCB Configuration
Layout View
Rev. V1
Cross Section View
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 .008” (0.20 mm) yielding a 50
Ω
lines width of
0.015” (0.38 mm). The recommended RF metalization
is 1 ounce copper.
Designer’s Kit MAAMSS0045SMB
The MAAMSS0045SMB Designer’s Kit allows for immediate evaluation of M/A-COM’s MAAMSS0045. The
Designer’s Kit includes an MAAMSS0045 mounted on an evaluation board and five loose MAAMSS0045’s. The
evaluation board consists of the recommended external surface mount circuitry, RF connectors, and a DC
multi-pin connector, all mounted to a multi-layer FR-4 PCB. The MAAMSS0045SMB evaluation PCB is
illustrated below with all functional ports labeled.
