Designed for use in both high-peak and high-m ean power applications,TEMEX differential phase shift
circulators offer high isolation while m aintaining low-insertion loss.
These ruggedly constructed circulators can operate under the m ost severe environm ental conditions,
according to MIL-SPEC.
The addition of specific heat sinks, or liquid cooling jackets increases m ean power handling;
for exam ple, of up to 200 kW-CW at 1.250 GHz.
Casting techniques can be used for pressurized waveguide in order to reduce leakage and weight,
especially for airborne radar.
In-house ferrite m aterials facilities, com puter-aided design, and experienced research and
developm ent team s, allow TEMEX to offer custom ers specific designs with optim al features.
With the addition of a suitable waveguide load and a dum my load on the appropriate port, a 4-port
differential phase shift circulator m ay be operated as a high-power isolator.
The reflected power that will be absorbed in the dum my load, or the output m ism atch - (V.S.W.R.)-
should be specified when ordering.
Options such as direction of circulation, m echanical output ports E-bend or H-bend are available upon
request.
