Bias Tee 25K-100MHz RF Biaser DC Blocker Coaxial Feed FOR Radio Frequency AM FM HF VHF Shortwave LNA Low Noise Amplifier BiasTee

Bias Tee 25Khz-100MHz RF Biaser DC blocker Coaxial feed FOR radio AM FM HF VHF shortwave LNA Low Noise Amplifier BiasTeeIn the broadband amplifier feed circuit, the high frequency is affected by the parasitic capacitance parameters, and the performance drops sharply, so the feed needs to use BiasTee. BiasTee consists of ultra-broadband, near-ideal, high-frequency inductors and capacitors without resonance points. DC blocking capacitor: block DC to prevent DC voltage from leaking to subsequent circuits or test instruments; High-frequency inductors: isolate AC information and prevent high-frequency signals from leaking to the power supply system. Application range A) Broadband Amplifier Some broadband amplifiers do not have a DC blocking capacitor inside, and the output terminal needs to be powered, so a biaser is required. Some amplifiers have built-in blocking capacitors, eliminating the need for an additional bias. B) Optical fiber communication, driver The driving current required by the diode is injected through the DC terminal of the bias; Communication data is injected through the RF side 1, operating frequency: 25Khz-100Mhz 2. Insertion loss <1dB 3, working voltage :DC1-50V 4, the maximum operating current n: <0.5A 5 . Interface: SMA
