Overview:
This proposal is intended to design a system that shall operate over a frequency range of 1 MHz to 6000 MHz with a tunable frequency bandwidth from 200 KHz to 56 MHz. There shall be signal processing algorithms, baseband processing techniques needed along with provision to port user specific algorithms and modulation schemes. Wide range of applications such as long range and short-range communications can be done from ground to ground applications.
Software Defined Radio:
The Software Defined Radio will enable test and development of modern and next generation radio technologies with the hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. The user developed Embedded modules shall be ported on to the integrated ARM processor.
The Transceiver module use a direct conversion architecture that should achieve high modulation accuracy with ultralow noise figures. The transmitted design should allow significant system margin for the external power amplifier (PA) section. The on board Transmit power monitor should have provision such that it operates at highly accurate Tx power and does the power measurements.
Intended Customer: Defence Electronics Labs, RF Communication

- RF Transceiver Module
- Clock In/ Out
- Audio Interface Module
- Mechanical Enclosure
