Teledyne Relays has published a white paper demonstrating how their high performance electromechanical relays support transmission of digital signals at a data rate of 10Gbps, delivering superior, repeatable insertion loss.

The paper describes how Teledyne, in conjunction with two customers, assessed the performance of the Series GRF300 and GRF303 high-repeatability, broadband TO-5 relays when used in test & measurement applications. The trials have been summarised using an eye diagram to demonstrate the relay capabilities.

The eye diagram is an oscilloscope display of a digital signal, repetitively sampled to display the behavior of the device under test. The basic information contained in the eye diagram is the amount of distortion (set by signal-to-noise ratio), time variation of zero crossing and the signal-to-noise at the sampling point. The most important features of the eye diagram are the size of the eye opening (signal-to-noise during sampling) and the magnitude of the amplitude and timing errors.

When mounted on impedance matched transmission lines, Teledyne Relays’ GRF300/GRF303 relays exhibited their most valuable characteristic, a monotonic insertion loss (S21) of its signal path to the maximum useful bandwidth, up to 19–21GHz.
