RF Bias Tee 50M-10GHz with DC Block - Coaxial Bias Injector for HAM Radio Amplifier Antenna LNA & Satellite LNB Power Supply

Broadband RF Bias Tee – 10MHz–10GHz, DC Bias Injector, RF Isolator, Bias Tee ModuleProduct Description:This broadband RF bias teeis designed to inject DC bias or power into RF signal paths while maintaining excellent RF performance across a wide frequency range from 50MHz to 10GHz. It features low insertion loss, high DC voltage and current handling, and a compact mini form factor. With SMA female connectorsfor both RF and DC ports, this bias tee is ideal for powering active RF components such as broadband amplifiers, laser diodes, and other devices that require DC bias injection without disturbing the RF signal.Key Features:Wide Frequency Range: 50MHz – 10GHzHigh DC Voltage Handling: Up to +35VHigh DC Current Handling: Up to 280mALow Insertion Loss:≤0.4dB @ 2.4GHz≤0.6dB @ 8GHz≤1.2dB @ 10GHzImpedance: 50ΩConnectors: SMA Female (socket) for both RF and DC portsCompact Size: 25 × 15 mm (excluding connectors) – mini designLightweight: Approx. 10gApplications:A) Broadband AmplifiersSomebroadband amplifiers do not have internal DC blocking capacitors andrequire external DC bias injection at the output. A bias tee isessential for such amplifiers.For amplifiers with built-in DC blocking capacitors, an external bias tee is not required.B) Fiber Optic Communications & Laser DriversLaser diodes require DC drive current, which can be injected through the DC port of the bias tee.Communication data is applied through the RF port, allowing simultaneous DC bias and high-speed signal transmission.Operating Principle:A bias tee consists of an ultra-wideband, high-frequency inductor and a DC blocking capacitor designed to avoid resonances within the operating band.DC Blocking Capacitor: Prevents DC voltage from leaking into the RF path, protecting downstream circuits and test equipment.High-Frequency Inductor: Isolates AC/RF signals, preventing high-frequency energy from coupling into the DC power supply.This configuration ensures clean RF performance while providing a stable DC bias path.Applications:Powering broadband RF amplifiers with no internal DC blockingLaser diode biasing in fiber optic communication systemsActive antenna biasingTest and measurement setups requiring DC bias injectionResearch and development labsRF module integration and prototypingImportant Notes:Ensure DC voltage and current do not exceed specified maximum ratings to prevent damage.The RF and DC ports are clearly marked; do not reverse connections.
