Software-Defined Transceiver Based on Single-Board RIO


Designing a low-cost, high-performance modem with a narrow bandwidth and a high data rate to be used in an oil pump control and monitoring application.
SDR architecture allows changing and fine-tuning parameters of the transceivers, including radio parameters in the field, avoiding the need for hardware changes.
The transceiver provides data communication between different objects for the development of complicated distributed systems with uniform traffic distribution and flexible network tuning capabilities.
In the design of the modem we have used IQ Modulator AD9957, Synthesizer ADF4360-8 and Precision adjustable LDO-regulator ADP3334 of the Analog Devices Company.


Using the SDR transceiver as a modem you can improve data throughput up to 100 kbps using the available communication infrastructure within the same radio channel of 18 kHz bandwidth.
