Wideband amplifier feed circuit, the high frequency is affected by the parasitic capacitance parameters, and the performance drops sharply, so the feed needs to use bias tee. Some broadband amplifiers do not have a DC blocking capacitor inside, and the output needs to be powered. A bias tee is required. Bias Tee consists of ultra-wideband, near idealized, high frequency inductors and capacitors without resonance points. Features: High quality, sturdy and durable. It consists of high frequency inductors and capacitors with ultra-wideband, near idealized and no resonance points. Isolated Capacitor: Isolate DC to prevent DC voltage from leaking to subsequent circuits or test instruments. High frequency inductance: Isolation of AC information to prevent high frequency signals from leaking into the power system. Applications: Broadband amplifiers, fiber optic communications, optical modulation drivers, and other test and measurement applications. Specification: Material: PCB Working Freq: 25k-100MHz Insertion-loss: <1dB Operating Voltage: DC5V Maximum working current: <0.6A Size: approx. 5.9 * 2.3 * 0.3cm / 2.32 * 0.91 * 0.12in Weight: 6.6g Package list: 1 * Bias Tee .
