Model 854-252-BLK is a 50 Ω inner DC Block with a 10 – 2000 MHz operating frequency range and 0.4 dB maximum insertion loss. The maximum VSWR is 1.35:1, the maximum voltage is 100 Vdc and the RF connectors are BNC female / BNC female. This model was designed to clean up Airband Radio interference issues.
DC Blocks allow RF to pass through a circuit with minimal interference while preventing DC from passing through the circuit. Applications include ground loop elimination, signal source modulation leakage suppression, system signal-to-noise ratio improvement, and test setup isolation. Inner DC Blocks are realized by placing a capacitor of varying capacitance in series with the center conductor. The required frequency range, voltage breakdown and desired insertion loss determine the capacitance value selected.
BroadWave Technologies offers DC Block solutions in 50 and 75 Ω impedances with a variety of standard RF connector combinations. Between series RF connector configurations are available upon request. Please contact us with your unique requirement for the appropriate model number.
