RoHS COMPLIANT
5.8-17GHz Low Noise Amplifier
GaAs Monolithic Microwave IC in SMD leadless package Description
The CHA3666-QAG is a two-stage self-biased wide band monolithic low noise amplifier. The circuit is manufactured with a standard pHEMT process: 0.25m gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is supplied in lead-free package.

The reference planes are defined from the footprint of the recommended characterization board shown below under the number 96272. The reference is the symmetrical axis of the package. The input and output reference planes are located at 2.65mm offset (input wise and output wise respectively) from this axis. Then, the given Sij incorporates this land pattern.
