Abstract
A switching arrangement for use at very high frequencies (gigahertz) consists of a number of four port microstrip switches interconnected to provide a versatile routing matrix. The use of P.I.N. diodes in each switch provides low insertion loss and also high isolation between different routes. The arrangement can be made in a very compact form.
