Maxim Integrated MAX9947 AISG
Maxim Integrated's MAX9947 is the industry's first AISG-compliant fully integrated transceiver for base stations and tower equipment. The Maxim Integrated MAX9947 AISG integrated transceiver, which is the Electronic Products Magazine Product of the Year, offers a typical dynamic range of 20dB and integrates a bandpass filter that operates in the 2.176MHz frequency with a narrow 200kHz bandwidth. The MAX9947 transmitter integrates a bandpass filter that is compliant with the 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. The MAX9947 AISG integrated transceiver also features a direction output to facilitate the RS-485 bus arbitration in tower-mounted equipment. This Maxim Integrated device is designed for use in base stations and tower equipment.
