MAX2057 Evaluation Kit
General Description
The MAX2057 evaluation kit (EV kit) simplifies evalua-
tion of the MAX2057 general-purpose, high-perfor-
mance, variable-gain amplifier with analog gain control.
The EV kit is fully assembled and tested at the factory.
Standard 50Ω SMA connectors are included at the
input and output of the EV kit to allow quick and easy
evaluation on the test bench.
This data sheet provides a list of equipment required to
evaluate the device, a straightforward test procedure to
verify functionality, a circuit schematic for the kit, a bill
of materials (BOM) for the kit, and artwork for each
layer of the PC board.
Features
♦ Analog Gain Control
♦ Up to 42dB Gain-Control Range
♦ 1700MHz to 2500MHz Frequency Range
♦ Fully Assembled and Tested
♦ Input and Output Internally Matched to 50Ω Over
Entire Band Of Operation
♦ 50Ω SMA Inputs and Outputs for Easy Testing of
All MAX2057 Features
