Overview
PA2423MB 2.
4 GHz Bluetooth Class 1 Power Amplifier IC Production Information Applications Bluetoothtm Class 1 USB Dongles Laptops Access Points Cordless Piconets Product Description A monolithic, high-efficiency, silicon-germanium power amplifier IC, the PA2423MB is designed for class 1 Bluetoothtm 2.
4 GHz radio applications.
It delivers +22.
7 dBm output power with 45% power-added efficiency – making it capable of overcoming insertion losses of up to 2.
7 dB between amplifier output and antenna tm input in 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 turnon/off switching of amplifier output with less than 3dB overshoot, meeting the Bluetoothtm specification 1.
1.
The PA2423MB operates at 3.
3V DC.
At typical output power level (+22.
7 dBm), its current consumption is 125 mA.
