Description
M/A-COM’s AM55-0016 is a high dynamic range,
switchable low noise amplifier in a low cost, MSOP
8-lead, surface mount, plastic package. The design
utilizes a patented switching technique to provide a
low insertion loss, high input IP3 bypass state in
parallel with the high gain, low noise state.

Description
The LNA employs external input matching to obtain
optimum noise figure performance and operating
frequency flexibility. The AM55-0016 also features
flexible biasing to control the current consumption
vs. dynamic range trade-off. It’s current can be
controlled over a range of 10 mA to 30 mA with an
external resistor.

Evaluation Board
The DC connector on the Designer’s Kit PCB
allows convenient DC line access.
This is
accomplished by one or more of the following
methods:
1. A mating female multi-pin connector (Newark
Electronics Stock # 46F-4658, not included).
2. Wires soldered to the necessary pins (not
included).
3. Clip leads (not included).
Handling Procedures
Please observe the following precautions to avoid
damage.
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.

Recommended PCB Configuration
The PCB dielectric between RF traces and RF
ground layers should be chosen to reduce RF
discontinues between 50 Ω lines and package pins.
M/A-COM recommends an FR-4 dielectric
thickness of 0.008” (0.2 mm) yielding a 50 Ω line
width of 0.015” (0.38 mm). The recommended
metallization thickness is 1 ounce copper.
