K261/V261 DC Blocks

Precision DC Blocks


These ultra-wide bandwidth DC Blocks have been optimized for optical communications and other high-speed pulse, data or microwave applications. Designed to apply AC drive signals to a device while eliminating any DC components, these DC Blocks feature wide bandwidth, excellent low frequency response, minimum insertion loss and flat group delay. Precision K Connector® interfaces assure excellent impedance match across the wide band-widths available. A one year warranty is provided.
