This is an example of measuring the transmit and receive paths on a beamformer IC, performing the bi-directional test with the device connected once - in a single orientation. For the Tx power amplifier (PA) we are able to characterize S-parameter, 1dB compression, 3rd order intercept and intermodulation distortion. On the Rx low noise amplifier (LNA) we again measure S-parameter, 3rd order intercept and intermodulation distortion, plus noise figure.
