Ready-to-Use Semi-Rigid Test Probes Up to 6 GHz

 

Pasternack has introduced a new line of semi-rigid test probes designed to assist in testing microwave circuits. By soldering the outer conductor to the signal ground and the exposed center conductor to the trace carrying the signal of interest, sampling measurements with these probes can be made without having to create a separate subassembly circuit board or add a connector … [Read more...]

Feed Horn for Square Kilometer Array (SKA) Developed

 

(May, 2016) Chalmers University in Sweden has recently delivered a new feed horn design for the Square Kilometer Array radio telescope to eventually be built in South Africa and Australia. The new feed horn incorporates low noise technology based on nanotechnology that does not require special low-temperature cooling. The feed horn was designed to cover 350 to 1050 MHz, the … [Read more...]
