AM50-0003
High Dynamic Range Low Noise Amplifier
800 - 1000 MHz
Recommended PCB Configuration
Cross Section View
Rev. V5
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 rec-
ommends an FR-4 dielectric thickness of 0.008” (0.20
mm) yielding a 50 Ω line width of 0.015” (0.38 mm).
The recommended RF metalization thickness is 1
ounce copper.
Designer’s Kit AM50-0003SMB
The AM50-0003SMB Designer’s Kit allows for immediate evaluation of M/A-COM’s AM50-0003. The Designer’s
Kit includes an evaluation board with mounted AM50-0003 and five loose AM50-0003’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 AM50-0003SMB evaluation PCB is illustrated below with all functional
ports labeled.

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:
A.) A mating female multi-pin connector
(Newark Electronics Stock # 46F-4658, not included).
B.) Wires soldered to the necessary pins (not included).
C.) Clip leads (not included).
