SMA Direct-Current Isolator (100k-18GHz) Technical Specifications

Isolator, a high-voltage capacitor; interface types include: N, SMA, F. Working Principle: Used to interpose in transmission lines to isolate the effect of DC power supply on signal sources and test equipment, enabling the transmission of microwave signals and isolation of DC signals, preventing damage to instruments and equipment from DC surges.

Application: Widely used for protecting against direct current in wireless RF (WIFI, Bluetooth, wireless network cards, etc.) testing equipment, such as IQFLEX, IQ2010, IQVIEW, network analyzers, signal simulators, and more; features wide bandwidth and low loss. This product is easy to install, performs well, and can interrupt direct current in the circuit without affecting microwave signal transmission.
