1. In The Broadband Amplifier Feed Circuit, The High Frequency Is Affected By The Parasitic Capacitance Parameters And The Performance Sharply, So The Feed Needs To Use Biastee. 2. Biastee Is Composed Of Ultra-Wideband, Near-Perfect , High-Frequency Inductors And Capacitors Without Resonance Points. 3. Dc Blocking Capacitor: Blocks Dc To Prevent From Leaking To Subsequent Circuits Or Test Instruments; 4. High-Frequency Inductor: Isolates Ac Information And Prevents High-Frequency Signals From Leaking To The Power Supply System. 5. Broadband Rf Feeder Rf Dc Blocker Biaser Feed Bias Tee 10mhz-6gh Product Application: A) Broadband Amplifier Some Broadband Amplifiers Do Not Have Dc Blocking Capacitors Inside, And The Output Needs Power Supply And A Biaser. Some Amplifiers Have Built-In Blocking Capacitors, Eliminating The Need For Additional Biasers. B) Optical Fiber Communication, Laser Driver The Driving Current Required For The Laser Diode Is Injected Through The Dc Terminal Of The Biaser; Communication Data Is Injected Through The Rf Side. Product Size: About 100x 45mm Product Interface: Sma External Screw Inner Hole Note:Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Colour:As Shown Material:Metal+Plastic Package Contents: 1 x RF Injector Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
