Description
These compact broad band couplers operate over frequency
bandwidths of 12 to 1 up to 36 to 1. Each coupler is
constructed in a rugged aluminum housing with Stripline
circuitry. The input, output and coupled output ports are
stainless steel SMA connectors. The isolated port is
terminated with a non-removable precision 50 ohm
termination. Custom variations of these designs to specific
requirements can also be produced.
