Features: Boost Your RF Signal: Our DC- Bias Tee- Injector separates your RF signal from DC- power, allowing for clearer and stronger- signal. High-Quality Material: Made of durable metal, our bias tee- injector is built- to last and withstand the rigors of daily use. Versatile Usage: Use our bias tee- injector in a variety of settings, including in labs, workshops, and even at home-. Enjoy Better Signal Quality: With our high-performance DC Bias Tee- Injector, you'll enjoy better signal quality and faster data transfer rates. Purpose：RF power supply for active antennas；Output isolation of broadband amplifiers；Communication data is injected through the RF terminal- Specifications: Size:approx 92mmx30mmx27mm/3.62x1.18x1.06in（Including N-connector Size） Material: Metal Frequency range: 100K-200MHz Insertion loss: 0.05dB@1MHz 0.08dB@100MHz (Refer to the actual measurement of S11 and S21 parameters for details-) Check the standing wave ratio and transmission parameters Maximum-voltage: 50V Maximum-current: 1000mA RF connector: N-head (default shipping capacitor end is male head, feed end is female head) System impedance: 50ohms Weight: 93g Wiring methods 1. DC -: External DC power supply 2. RF: RF signal terminal- (this port can only transmit RF signals) 3. RF+DC: RF DC bias (this port can transmit RF and DC bias) 4. GND- shrapnel: DC powered common ground terminal- 5. VCC through core capacitor: the power- supply terminal- of DC power supply Package Includes: 1PC DC Bias DC Block note: 1.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you place order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
