TRAK offer new variants of its highly popular range of space qualified WR28 Isolators & Circulators. These are available in form factors that offer iMUX or LNA/ converter designer maximum mechanical flexibility.
The WR28 Isolators & Circulators, which operate from 27-31 GHz, can be configured by TRAK, or by the customer, to become an Isolator by the addition of a TRAK termination. As the devices are symmetrical along the broad-wall this means that any combination of clockwise or counter clockwise WR28 Isolators & Circulators can be realized to operate over 27-31 GHz with the minimum of stock holding.
|Operating Frequency||27.0 to 31.0||GHz|
|Operating Temperature||-20 to +80||C|
|Insertion Loss||0.10||dB max.|
|Return Loss||23.0||dB min.|
Note that each flange has through holes which does mean that the devices are a little larger than the standard 19.05mm (across the opposing ports) although alternative version with any combination of standard and non standard flange arrangement can be provided. The following is a typical room temperature plot at 10dBm input power.
