MAX9947ETE+T

The MAX9947ETE+T is a AISG integrated transceiver in 16 pin TQFN package. The receiver offers a typical dynamic range of 20dB and integrates a bandpass filter that operates in 2.176MHz frequency with a narrow 200KHz bandwidth. The transmitter integrates a bandpass filter that is compliant with AISG spectrum emission profile. It can modulate OOK signals up to 115.2kbps. The output power can be varied with external resistors from +7dBm to +12dBm to compensate for loss in the external circuitry and cabling. It also features a direction output to facilitate the RS485 bus arbitration in tower-mounted equipment. It is used in base stations and tower equipment.
