Isolators/Circulators

I-2111A

I2111AI4133CMSinclair's 1' series isolator and circulators offer superior performance in a compact rugged package. Careful temperature compensation and top quality Components ensure high isolation with very low insertion loss over their full operating temperature range, and offer a high degree of RF and magnetic stability. Circulators are supplied without loads. Isolators come equipped with a variety of load terminations.

The compact 1-4133CM and 1-4233CM feature internal load termination. Threaded holes in the steel casing allow surface mounting to any non-magnetic material.
Aluminum brackets can also be supplied to isolate the unit from mounting surface to increase their stability.
I4233CM
A variety of models are available factory-tuned in the 70, 150, 450 and 800 MHz frequency bands. I4222HPIn addition, field tunable isolators are available for the 138-174 and 406-430 or 450-470 MHz bands.
Suffix 'T' on applicable model numbers designates field tunable.

Note:
1-VSWR is reference to 50 ohms.
2-Specify model number and exact frequency when ordering: A= Factory Tuned, T= Field Tunable
3-Replace the * in the model number as follows:

  • 0 = Circulator (no load)
  • 1 = 15 Watt
  • 2 = 30 Watt
  • 3 =60 Watt

Standard dual Isolators are equipped with and additional 15 Watt load. HP versions have an additional 30 Watt load.

1-Load power deratings determine maximum power reflected into output port of isolator without damage to unit (Load B for dual Isolators).
