Your Contact For Higher Performance

The Pad ROL™100A offers the best-in-

class electrical performance for testing

your most demanding RF/microwave

communications devices to 40 GHz.

Whether you’re performing engineering

tests on high gain RF amplifiers, RF

transceivers, the latest WiMAX or 3G

devices, the Pad ROL™100A delivers.

Engineered with robust mechanical

performance, the Pad ROL™100A meets

your most demanding production needs

for higher First Pass Yield, longer MTBA,

and lower cost of test. New contact

designs for 0.4mm and >0.5mm pitches

provide longer contact life and longer

MTBA for testing your QFN and DFN

matte tin and NiPdAu packages.
