Key Featrues
4:1 Multiplexer: Facilitates connectivity between a single modem and up to four RF ports, reducing the need for additional hardware and simplifying system design in multi-port applications like antenna arrays.
Adjustable Receiver Sensitivity: Allows sensitivity to be fine-tuned from -20.5dBm to -15dBm, accommodating power loss through external components like splitters and enhancing signal reliability in challenging environments.
Adjustable Transmitter Output Power: Offers output power control from -0.5dBm to +7.0dBm, enabling compensation for external circuitry losses and optimizing signal strength for long-distance communication.
Wide Operating Temperature Range (-40°C to +105°C): Ensures reliable performance in extreme environmental conditions, making it suitable for outdoor applications such as tower-mounted amplifiers and base stations.
Applications
Base Station Control Systems: The MAX11947 is well-suited for base station single and multi-primary controllers, providing robust AISG v3.0-compliant communication. Its adjustable transmitter output and receiver sensitivity ensure optimal performance across varying cable lengths and signal losses, making it a reliable choice for modern cellular infrastructure.
RS-485 Half-Duplex Coaxial Links: The MAX11947 excels in RS-485 half-duplex communication systems, offering a wide dynamic range and adjustable sensitivity for reliable data transfer. Its autodirection output simplifies bus arbitration, making it ideal for tower-mounted equipment and other industrial communication applications.
2MHz OOK Modem Applications: The MAX11947 is perfect for 2MHz OOK modem applications, providing backward compatibility with AISG v2.0 data rates (9.6kbps, 38.4kbps, and 115.2kbps). Its integrated bandpass filter and adjustable output power make it suitable for antenna arrays and other RF communication systems requiring precise signal modulation.
