Mar 23, 2020 · The circulator is perhaps the strangest, it is a 3 port device, sort of a traffic roundabout for radio waves, and can either be used as a transmit / receive seperator, or, it can send reflected power due to vswr to a dummy load.

Dual junction circulators

Dual junction circulators

Jun 07, 2020 · Dual-junction circulators are used in duplexing transmitter/receiver to antenna, in radar applications. The purpose of the second junction is to isolate the power amplifier from seeing a poor impedance match and preventing load pull which could blind your radar. Many comms systems use a diplexer scheme, because transmit and receive are .
