QN8026
High Performance Full Duplex FM Transceiver for Portable Devices
__________________________ General Description __________________________
The QN8026 is a high performance, low power, fully integrated single-chip stereo full duplex FM transceiver designed for
cell phones, PMP/PNDs, and portable radios. It integrates both FM receiving and transmitting functions, auto-seek and clear
channel scan, and antenna tuning to ease matching in real applications. Advanced digital architecture enables superior
receiver sensitivity, crystal clear audio.
With its small footprint, minimal external component count and multiple clock frequency support, the QN8026 is easy to
integrate into a variety of small form-factor low power portable applications. An integrated voltage regulator enables direct
connection to a battery and provides high PSRR for superior noise suppression. A low-power Standby mode extends battery
life. ESD protection is on all pins. The QN8026 is fabricated in highly reliable CMOS technology.
