FUNCTIONAL PIN DESCRIPTION
Name
Pin #
Description
RF IN
2,3
RF input for the power amplifier. This pin is AC-coupled to the transistor base of the first stage.
VB1
4
Bias current control voltage for the first stage.
VB2
6
Bias current control voltage for the second stage.
VB3
7
Bias current control voltage for the third stage. The VB3 pin can be connected with the first and second
stage control voltage (VB1,VB2) into a single reference voltage (referred to as Vref) through an
external resistor bridge.
Supply voltage for the bias reference and control circuits. The VCC feed line should be terminated with
a 10 nF bypass capacitor close to connector pin. This pin can be combined with VC1, VC2 and VC3
pins, resulting in a single supply voltage (referred to as Vc).
RF output for the power amplifier. This pin is DC-decoupled from the transistor collector of the third
stage.
Power supply for first stage amplifier. The VC1 feedline should be terminated with a 120pF bypass
capacitor, followed by a 10 Ohm resistor. This pin can be combined with VC2,VC3 and VCC pins,
resulting in a single supply voltage (referred to as Vc).
Power supply for second stage amplifier. The VC2 feedline should be terminated with a 47 pF bypass
capacitor, followed by a 5 Ohm resistor. This pin can be combined with VC1,VC3 and VCC pins,
resulting in a single supply voltage (referred to as Vc).
Power supply for the third stage amplifier. The VC3 feedline should be terminated with a 120 pF
bypass capacitor. This pin can be combined with VC1,VC2 and VCC pins, resulting in a single supply
voltage (referred to as Vc).
