The LMH730227, LMH730216 and LMH730165 evaluation
boards are designed to aid in the characterization of National
Semiconductor's High Speed monolithic amplifiers.
Use the evaluation boards as a guide for high frequency lay-
out and as a tool to aid in device testing and characterization.
The evaluation boards accommodate general purpose am-
plifiers, as well as amplifiers with the following features:
The evaluation board schematic is shown below. Refer to the
product data sheets for recommendations for component val-
ues.

BASIC OPERATION
These boards have identical circuit configurations and are
designed to accommodate both non-inverting and inverting
operation. By changing RT or RIN and ROUT different input
and output impedances can be matched. The SMA connec-
tors and board traces are optimized for 50Ω operation, how-
ever other impedances can be matched as shown below.
