Description
Bias control for the first stage. Needs to be divided down from its nomi-
nal value of 2.5V using a resistive divider network of 240k
and
360k
. V
REG1
and V
REG2
may be adjusted to minimize idle current for
a given output power. Alternative V
REG
voltages can be used as
defined on the application schematic.
Supply for bias circuits.

VREG2
Bias control for the second stage. Needs to be divided down from its
nominal value of 2.5V using a resistive divider network of 240k
and
240k
. Alternative V
REG
voltages can be used as defined on the appli-
cation schematic.
Second stage bias circuit source. For best linearity, decouple with
bypassing capacitors of 15pF and 100nF.
Connect to ground plane via a 15nH inductor. DC return for the second
stage bias circuit.

RF output and power supply for the final stage. This is the unmatched
collector of the final stage. It requires an output matching network,
including a DC blocking capacitor.

Ground connection. The backside of the package should be soldered
to a top side ground pad which is connected to the ground plane with
multiple vias. The pad should have a short thermal path to the ground
plane.
