Access Points
Cordless Piconets
Product Description
A monolithic, high-efficiency, silicon-germanium
power amplifier IC, the PA2423L is designed for
class 1 Bluetooth
tm
2.4 GHz radio applications. It
delivers +22.5 dBm output power with 45%
power-added efficiency 鈥?making it capable of
overcoming insertion losses of up to 2.5 dB
between amplifier output and antenna input in
tm
class 1 Bluetooth applications.
The amplifier features:
an analog control input for improving PAE at
reduced output power levels;
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 3.3V DC. At typical
output power level (+22.5 dBm), its current
consumption is 125 mA.
The silicon/silicon-germanium structure of the
PA2423L 鈥?and its exposed-die-pad package,
soldered to the system PCB 鈥?provide high
thermal conductivity and a subsequently low
junction temperature. This device is capable of
operating at a duty cycle of 100 percent.
Features
+22.5dBm at 45% Power Added Efficiency
