Notes about testing the RF5110G
The test setup shown above includes two attenuators. The 3dB pad at the input is to minimize the effect on the signal genera-
tor as a result of switching the input impedance of the PA. When V
change can cause the signal generator to vary its output signal, either in output level or in frequency. Instead of an attenuator
an isolator may also be used. The attenuator at the output is to prevent damage to the spectrum analyzer, and should be sized
accordingly to handle the power.
It is important not to exceed the rated supply current and output power. When testing the device at higher than nominal supply
voltage, the V

A buffer amplifier is recommended because the current into the V
changes with voltage. As an alternative, the voltage may be
monitored with an oscilloscope.
