PA2423L
2.4 GHz Bluetooth Class 1 Power Amplifier IC
Preliminary Information
Using V
CTL
V
is an analog pin that is designed to control the gain of PA2423L. Applying a voltage between 0V and
CTL
Vcc will adjust the gain between -15dB and 21 dB. Used in combination with a variable drive level to
tm
PA2423L, the V
function can greatly optimize the PAE of the system at all four Bluetooth
transmitted
CTL
power levels.
By applying approximately 1.4V to V
, for example, a Class1 radio can be modified to a Class2 radio with
CTL
the PA2423L consuming only 15mA.
tm
By implementing a resistor DAC, the V
pin can interface with Bluetooth
transceivers offering digital and
CTL
programmable outputs.
