1 / 10 page  PA2423L RangeCharger TM 2.4 GHz Power Amplifier IC Final 13-DST-01 Rev 4.0 Jun-14-2006 1 of 10 QA061406 Applications Bluetooth tm wireless technology (Class 1) USB dongles PCMCIA, flash cards Access points 2.4GHz cordless telephone Features +22.5 dBm at 45% Power Added Efficiency Low current 80 mA typical @ POUT = +20 dBm Temperature stability better than 1 dB over -40 °C to +85 °C Power-control and power-down modes 3.3 V single supply operation Small lead-free, plastic package: 6 lead QFN (1.6 mm x 3.0 mm) Ordering Information Part Number Package Remark PA2423L 6 Pin QFN Samples PA2423L-R 6 Pin QFN Tape & Reel PA2423L-EV Evaluation Kit 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.
