Description
RF IN
2, 3
RF input for the power amplifier. This pin is DC-shorted to GND but AC-coupled to the transistor
base of the first stage. For 5.15-5.35GHz this pin is pre-matched to 50
.
Bias current control voltage for the first stage.
Bias current control voltage for the second stage. The VB2 pin can be connected with the first
stage control voltage (VB1) into a single reference voltage (referred to as Vref) through an
external resistor bridge(R1/R2).
Supply voltage for the bias reference and control circuits. The VCC feed line should be
terminated with a 1
μ
F bypass capacitor as close to the device as possible. This pin can be
combined with both VC1 and VC2 pins, resulting in a single supply voltage (referred to as Vc).
RF output for the power amplifier. This pin is AC-coupled and does not require a DC-blocking
capacitor.
Power supply for first stage amplifier. The VC1 feedline should be terminated with a 220pF
bypass capacitor as close to the device as possible, followed by a 1
μ
F bypass capacitor at the
supply side. This pin can be combined with VC2 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 220pF
bypass capacitor as close to the device as possible, followed by a 1
μ
F bypass capacitor at the
supply side. This pin can be combined with VC1 and VCC pins, resulting in a single supply
voltage (referred to as Vc).
The center metal base of the MLP package provides both DC and RF ground as well as heat
sink for the power amplifier.
