Customers may select one of several connector types for most LadyBug sensors. This often allows the sensor to be placed directly on the customer’s DUT, increasing measurement accuracy by eliminating adaptors. Connectors are installed and the VSWR is verified at the beginning of the sensor’s manufacturing process. Field replacement is not recommended and voids the warranty because it could degrade the VSWR and calibration.
Connector compatibility
We have carefully chosen small form connector types to provide the best service for customers. Our standard and optional small form connectors are 3.5mm, SMA and 2.92mm. All three types are rated for mating with each other and match performance is similar to the lesser connector, and in some cases exceeds it.
Our SMA connectors are high performance Super SMA connectors. These connectors have a long lifetime with a connects/disconnects rating similar to that of 3.5 mm connectors. Our connectors are rated for thousands of connects & disconnects.
