Extended-K Sparkplug Launcher Connector


The EK102M-R male sparkplug launcher connector is designed as a screw in launcher enclosed in a microwave circuit housing. Like all Anritsu launchers, they can be easily removed for replacement or repair without unsoldering the glass bead and interface to the microwave circuit.

The EK102M-R provides frequency scalability from DC to 43.5 GHz with traceable and mode-free performance, establishing a solid uncertainty budget backed by quality assurance to a national metrology lab as well as eliminating the possibility of incorrect measurement data at a resonance point respectively.

Designed for applications that extend past 40 GHz, this connector will eliminate the needless migration from 2.92 mm to more expensive 2.4 mm connectors when operation beyond 43.5 GHz is not warranted. All Anritsu connectors are MIL-PRF-39012 and MIL-STD-202 rated, ensuring high reliability and robustness for the harshest testing environments.

From component interfaces to PCB launches, the EK101M-R provides low insertion loss and good return loss. All EK102M-R connectors have guaranteed specifications, providing the true parameter performance with a 99% level of confidence.
