Ultra-Wideband Bias Tees Model Number: K251/V251 Frequency Range: 50 KHz to 65 GHz

www.profiua.com Anristu Ultra-Wideband Bias TeesUltra-Wideband Bias Tees
Model Number: K251/V251
Frequency Range: 50 KHz to 65 GHz


These ultra-wide bandwidth bias tees have been optimized for optical communications and other high-speed pulse, data or microwave applications. Designed to simultaneously apply both DC and RF drive signals to a device via a single input port, these bias tees feature fast rise times, excellent low frequency response, minimum insertion loss and flat group delay. Precision K Connector® and V Connector® interfaces assure excellent impedance match across the wide band-widths available. A one year warranty is provided.
