Drop In Circulators Drop In Circulator Photo
Microwave Devices offers a wide range of drop-in circulators, designed specifically for use with stripline and microstrip circuits.

Many of our standard models are shown in the tables below. Custom units can also be provided.

(dB)
CD-850/100 800 - 900 50 1.28:1 0.6
CD-880/40 860 - 900 50 1.20:1 0.5
CD-880/160 800 - 960 50 1.28:1 0.6
CD-881.5/25 869 - 894 50 1.20:1 0.5
CD-1080/240 960 - 1200 50 1.20:1 0.5
CD-1300/200 1200 - 1400 50 1.20:1 0.5
CD-1485/110 1430 - 1540 50 1.20:1 0.5
CD-1750/100 1700 - 1800 50 1.20:1 0.5
CD-1850 /100 1800 - 1900 50 1.20:1 0.4
 Note: Unit isolation is equal to the match on port 3.
  Example: If port 3 return loss = 20 dB, then isolation = 20 dB.
