Features: 100% brand new and high quality 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. Application: Broadband amplifier, optical fiber communication, optical modulation drive, other test and measurement applications Specifications: Working frequency: 10MHZ-6GHz Insertion loss < 1.2 dB Operating Voltage: DC1-50V Normal working current: < 0.5A Size: 7 x 3.3cm / 2.76 x 1.30in Weight: 36g Package included: 1 x Bias Tee Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
