Matchbox Characterization

The Octiv Mono can be used to characterize the power efficiency and impedance range of match boxes.

RF Matching Network Characterization

Thin Film Process Transfer

The Quantum RFEA is a hybrid between an ion energy analyzer and quartz crystal microbalance, enabling it to directly measure the ion/neutral ratio impacting a substrate surface. This is one of the key parameters for transferring thin film processes between different tools.
