All of EiCs IPAs use the same evaluation board, bypass and DC blocking capacitors. The values
are the same for all the capacitors except for matching.
Matching circuits are described by the schematics. The values of the components are listed in the
bill of material.
The DC power connector consists of four pins. The two inside pins are for ground.
The Vref/pd pin of the IC can be used to set the amplifier in class A operation when connected to
5V, or varying degree of Class AB by adjusting the voltage lower (typically >3.0 volts). The bias
condition can also be set by varying the value of R1while keeping the Vref/pd at 5V.
The Vcc pin can operate up to 7 volts Vcc. The bias current can be adjusted by the reference
voltage or R1 value.
