BroadWave Technologies model 851-033-BLK is a 50 Ω Inner / Outer DC Block with a 10 MHz – 18 GHz operating frequency range. The maximum VSWR is 1.35:1, the maximum voltage is 200 Vdc and the RF connectors are SMA male / SMA female. Inner / Outer DC Blocks are realized by placing a capacitor of varying capacitance in series with the inner and outer conductors. The required frequency range, voltage breakdown and desired insertion loss determines the capacitance value selected. These devices allow RF to pass through a circuit with minimal interference while preventing DC to pass through the circuit. Solutions in 50 and 75 Ω impedances with a variety of RF connector combinations are standard. Custom impedances are available upon request. Please contact the factory with your unique requirement.
