Description
RF input – RF input, 50
Ω
(nominal). An external
DC block is required
Equipotential point – Internal circuit common,
which must be connected to the pcb ground or
common via the lowest possible impedance.
Bias adjust – 2nd stage –
Quiescent
current of
the second amplifier stage as measured at V
CC
2
can be increased by adding a resistor between
this pin and V
REG
. This pin may be left open if the
nominal value of collector current for the second
stage is acceptable. This pin should not be
connected to ground.
Regulated voltage input – The voltage applied
to this pin supplies the active bias stages for the
power amplifier stages. The nominal applied
voltage is equal to V
CC
. The power amplifier
stages are disabled if this pin is open.
Bias adjust – output stage –
Quiescent
current
of the output amplifier stage as measured at
V
CC
2 can be increased by adding a resistor
between this pin and V
REG
. This pin may be left
open if the nominal value of collector current for
the output stage is acceptable. This pin should
not be connected to ground.
Active detector supply voltage – The voltage
applied to this pin powers the active detector
circuit. The nominal applied value is equal to
V
CC
. The active detector circuit is disabled if
this pin is connected to ground.
Active detector reference voltage output – The
DC voltage produced at this pin can be used to
track the temperature drift of the voltage from
V
DET
. This voltage can be used to temperature
compensate the voltage from V
DET
.
Active detector output voltage – Detected output
voltage which varies proportionally to the output
power from the RF Out pins.
RF output – RF outputs, internally connected to
share signal currents. An internally-generated
DC voltage is present at this pin, so a DC
blocking capacitor should be included in the
output circuit.
No internal connection
Collector supply voltage 2 – The voltage applied
to these pins supplies the collector of the 2nd
amplifier stage. These pins are internally
connected to share current.
Collector supply voltage 1 – The voltage applied
to this pin supplies the collector of the input
amplifier stage.
