Taking D3I4080Y as an example, it operates from 4 to 8GHz and can handle average forward inputs up to 30W, peaking at 50W. Maximum reverse input power is 2W.

“The component provides more than 16dB of isolation and has an insertion loss of less than 0.4dB,” said the distributor,

Body size is 1 x 1 x 0.5inch (~25 x 25 x 13mm) plus connectors and terminator, and four options offer any combination of male and female SMA connectors on the input and output.

Applications are foreseen in laboratories, quantum computing and aerospace.
