Bias Tee 50M-10GHz RF DC Injector Blocking Coaxial Tee for LNA Amplifier SDR Ham Radio Antenna 868MHz LoRa Helium Hotspot Miner

RF Bias Tee 50MHz-10GHz SMA DC Injector Low Loss 35V 280mA CNC Coaxial Module for Amplifier LNA LaserProduct Description:This broadband bias tee (DC injector / coaxial bias tee) operates from 50MHz to 10GHz and is housed in a durable CNC‑machined aluminum enclosurefor excellent shielding. It allows DC bias or power to be added to an RF signal path with minimal insertion loss. The RF signal path and DC bias port both use SMA female connectors. Ideal for powering amplifiers, laser diodes, active antennas, and other RF components requiring clean DC injection without disturbing the high‑frequency signal.Key Features:Frequency Range: 50MHz – 10GHz (also suitable for 10MHz–10GHz applications, with spec starting at 50MHz)DC Voltage Rating: +35V maxDC Current Rating: 280mA maxInsertion Loss:≤0.35dB @ 2.4GHz≤0.6dB @ 8GHz≤1.2dB @ 10GHzImpedance: 50ΩConnectors: SMA female (RF in/out, DC port)Compact Size: 28 × 23.4 × 12mm (excluding connectors)Enclosure: CNC metal case with EMI shieldingApplications:Powering remote LNA / PA stages in RF front endsLaser diode biasing in optical communication systemsActive antenna power injectionTest & measurement setups requiring DC bias on RF linesBroadband amplifier feeding circuits
