Single Chip 58 GHz Radio Relay Front End

This article describes a solution for a low cost front end to be used in point to point radio relays operating in the uncoordinated 57.5 to 59 GHz frequency band. The main characteristics of the equipment operating in this band in Europe have recently been agreed in draft by the ETSI (December '99). This standard favors the use of the Time Division Duplex (TDD) scheme that allows for the design of a very simple front end. Implementation of the equipment as a whole is also presented together with link measurement results.
