Summary
Manpack devices are one of the important modules
that are used in different military situations. Frequency hopping has
been the main modulation scheme that is used in such devices due to the
benefits it provides for security purposes. The first Egyptian Frequency
Hopping Manpack system was developed in our department in collaboration
with the Egyptian military. The system was designed and assembled using
commercial components on printed circuits boards. The prototype has been
sampled, and field tested and is going through a first production phase.
This prototype has a few drawbacks that need to be addressed for future
generations. Size, weight, power consumption, frequency ranges and
hopping rate are among these issues. In this proposal, we are planning to
implement enhancements to this system in order to provide solutions for
these issues that can serve as the core of the second generation
Frequency Hopping Manpack System.
This project focuses only on the transceiver
side and its implementation. New specifications include frequency range
of 30MHz-500MHz and hopping rate of 300 hop/sec. In this project, a fully
integrated transceiver is planned to improve the system from all aspects.
Onchip integration reduces the size drastically and in case of mass
production, cost per unit also reduces dramatically. On-chip techniques
provide solutions for many problems and provide innovative techniques
that are mostly not possible in the discrete-component implementation. In
this proposal we are targeting a 10x reduction in cost for mass
production, which is not possible in the first prototype since all
components are off the shelf and their cost cannot be reduced unless they
are combined together or integrated as is the case in this work.
