Features Application: Broadband amplifier, optical fiber communication, optical modulation drive, other test and measurement applications. It consists of high frequency inductors and capacitors with ultra-broadband, near idealization and no resonant point. Isolating capacitance: isolating dc to prevent dc voltage from leaking to subsequent circuits or test instruments. High frequency inductance: isolate ac information to prevent high frequency signals from leaking into the power supply system. 100% brand new product, all refund if unsatisfied If you have any questions, please contact our professional customer service team.
