A hardware concept demonstrator has been built of a fast combined frequency and time hopping RF synthesiser for use in high security radio communications. The design involves the use of a recirculating switch breakable loop incorporating a fibre optic delay line and hop rates of greater than 33,000 Hops/sec have been demonstrated.
