High-Band Cascaded Test Guide

This section involves measuring the cascaded performance of the High Band LNA, High Band Mixer and High Band IF Amp using the Frequency Doubler. All tests apply for an IF output terminated into a 1 kΩ differential load. A transformer balun is used to match the IF output to the 50 Ω test equipment. All unused ports are terminated into 50 Ω.

Test setup Figure 20

The high band power conversion gain (dB) is the measured power (dBm) at the IF frequency minus the RF source power (dBm). It is measured using a RF source and a spectrum analyzer.

1)Set the RF source power (RF Pin) and the desired frequency (see Table 4). Connect the RF source to the EVM RF port, J20.
