GND Ground Connection (See Figure 3).
2 RFIN RF Input. DC couple RFIN and match it to 50 Ω (See Figure 4).
5, 7, 9, 11 V
to V
Drain Bias Voltage for the Power Amplifier (See Figure 5).
13 RFOUT RF Output. AC couple RFOUT and match it to 50 Ω (see Figure 6).
15 V
DET
Detector Voltage for the Power Detector (See Figure 7). V
DET
is the dc voltage representing the RF
output power rectified by the diode, which is biased through an external resistor. Refer to the typical
application circuit for the required external components (see Figure 40).
16 V
REF
Reference Voltage for the Power Detector (See Figure 7). V
REF
is the dc bias of the diode biased through
an external resistor used for temperature compensation of V
DET
. Refer to the typical application circuit
for the required external components (see Figure 40).
18, 20, 22, 24 V
GG4
to V
GG1
Gate Bias Voltage for the Power Amplifier (See Figure 8). For the required external components, see
Figure 40.
Die Bottom GND Ground. The die bottom must be connected to the RF/dc ground (see Figure 3).
