Common RF port. The terminal PC is connected to the terminal P1 or the
terminal P2 by the voltage supplied to the terminal VCTL1 and VCTL2.
This terminal is for DC power supply of the 1st stage of power amplifier. Please
place bypass capacitors C15 and C16 between this terminal and GND as near
as possible.
Control port. Please connect bypass capacitor C2 with ground plane close to
this terminal.
In order to block the DC bias voltage of internal circuit, external capacitor C1 is
required.
Control port. Please connect bypass capacitor C24 with ground plane close to
this terminal.
RF port. This terminal is one of ports of SPDT SW. This terminal connects to
PC terminal (pin 15) when logical low voltage signal is supplied to VCTL2 (pin
14) and logical high voltage signal is supplied to VCTL1 (pin 16). External
capacitor C23 is required to block the DC bias voltage of internal circuit.
Output terminal of power amplifier. The RF signal from power amplifier goes out
through an external matching circuit connected to this terminal. Moreover, this
terminal should be connected to DC power supply through inductor L9 shown in
the application circuit, since it is the terminal for power supply of the 3rd stage
of Power Amplifier.
This terminal is for DC power supply of the 2nd stage of power amplifier. Please
place bypass capacitors C17 and C18 between this terminal and GND as near
as possible.
Ground terminal (0V)
RF input terminal of power amplifier. An external matching circuit is required.
This terminal is for base bias supply of the 1st stage of power amplifier.
Operation current of the power amplifier is adjusted by changing the bias
voltage applied to this terminal. Please connect bypass capacitors C12 and C13
with ground plane close to this terminal. Please connect pin 24 and pin 1, and
connect the resistor R1 for temperature characteristic compensation of PA gain.
This terminal is for base bias supply of the 2nd stage of Power Amplifier.
Operation current of the power amplifier is adjusted by changing the bias
voltage applied to this terminal. Please connect bypass capacitors C12 and C13
with ground plane close to this terminal. Please connect pin 23 and pin 1, and
