21.5 dBm is output. In this time, the voltage ratio of VGG1 and VGG2 should match to the voltage ratio
generated by the resistance of the recommended gate bias circuit.

Recommended Current Adjustment Method
(1) VGG2/PIN separate adjustment
(VGG2 adjustment 1) (PIN adjustment 1) (VGG2 adjustment 2) (PIN adjustment 2)
When the RF input
(PIN) is off, the current
consumption (IDD) is
adjusted to 200 mA.
Variation of IDD and
POUT due to adjustment
The output power
(POUT) is adjusted
to 21.5 dBm.
IDD=200±20 mA
POUT=21.5 dBm
The current
consumption (IDD)
is finely adjusted to
200 mA.
IDD=200 mA
POUT=21.5±0.2 dBm
The output power
(POUT) is finely
adjusted to 21.5 dBm.
IDD=200±5 mA
POUT=21.5 dBm
(2) Simple adjustment
(IDD read) (VGG2 setting) (PIN adjustment)
When the RF input (PIN)
is off, the gate voltage
(VGG2) is set to 0.4 V
and it is read.
Variation of IDD and POUT
due to adjustment
The formula∗1where
VGG2=f (IDD: VGG2=0.4 V)
is used to set VGG2.

e.g. VGG2=a-b x IDD IDD=200±5 mA
The output power (POUT)
is adjusted to 21.5 dBm.
