FUNCTIONAL PIN DESCRIPTION
Name
Description
RF IN
RF input for the power amplifier. This pin is DC-shorted to GND but AC-coupled to the transistor base of the
first stage.
VB1
Bias current control voltage for the first stage.
VB2
Bias current control voltage for the second stage
VB3
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).
VCC
RF OUT
RF output for the power amplifier. This pin is DC-decoupled from the transistor collector of the third stage..
VC1
Power supply for first stage amplifier. The VC1 feedline should be terminated with a 120pF bypass capacitor,
followed by a 10 Ohm resistor
Power supply for second stage amplifier. The VC2 feedline should be terminated with a 47 pF bypass
capacitor, followed by a 5 Ohm resistor
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
VC2
VC3
DET_REF
Power detector reference output pin should be terminated with a 100 kOhm loading resistor
DET_PWR
Power detector output-coupled pin should be terminated with a 100 kOhm loading resistor
GND
The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the
power amplifier..
