Description

A simple test jig for the LNA stage of the AD8331/2/4 from Analog Devices:

http://www.analog.com/en/search.html?q=ad8331

http://www.analog.com/media/en/technical-documentation/data-sheets/AD8331_8332_8334.pdf

Using the AD LNA only model for the AD8331/2/4 from:

http://www.analog.com/media/en/simulation-models/spice-models/AD8331lna.cir

edited for EasyEDA compatibility.

The LNA symbol is an edited version of the full AD8331 symbol with the non-LNA pins removed and the spice pin ordering set to match the AD LNA model.
