Product Description
A monolithic, high-efficiency, silicon-germanium power
amplifier IC, the PA2423L is designed for 2.4GHz
wireless applications, including Bluetooth
TM
Class1 and
2.4 GHz cordless telephone applications. It delivers
+22.5 dBm output power with 45% power-added
efficiency, making it capable of overcoming insertion
losses of up to 2.5 dB between amplifier output and
antenna input.
The PA2423L contains an analog control input for
improving PAE at reduced output power levels.
The PA2423L provides a digital control input for
controlling power up and power down modes of
operation.
An on-chip ramping circuit provides the turn-on/off
switching of amplifier output with less than 3dB
overshoot, meeting the Bluetooth
TM
specification 1.1.
The PA2423L operates at 3.3 V DC. At typical output
power level (+22.5 dBm), its current consumption is
125 mA.
The silicon/silicon-germanium structure of the PA2423L,
and its exposed die-pad package, soldered to the
system PCB, provide high thermal conductivity and a
subsequently low junction temperature. This device is
capable of operating at a duty cycle of 100 percent.
