Model 859-173-BLK is a 50 Ω inner DC block with an operating frequency range of 10 to 2500 MHz and exhibits 1.50:1 maximum VSWR. Insertion loss is 0.4 dB maximum, and the maximum blocking voltage is 100 Vdc. The RF connector configuration is N male / BNC female. DC blocks allow RF to pass through the unit but do not allow DC to pass through the unit.

Applications for these devices include ground loop elimination, signal source modulation leakage suppression, system signal-to-noise ratio improvement, test setup isolation and other situations where undesired DC or audio current flows within a system such as the input or the output of an amplifier to prevent loading of the bias voltages.

BroadWave DC blocks are available in a wide range of frequency ranges, connector types as well as 50 or 75 Ω standard impedances (other impedances are available upon request). Below is a summary of our current DC Block capabilities:

● 50 Ω and 75 Ω DC Blocks are standard (other impedances are available)
● Low insertion loss
● Inner, outer, and inner/outer DC Blocks are available
● Virtually any RF connector combination (BNC, SMA, N, TNC, F, reverse polarity, and others)
● Custom designs are also available. Please consult the factory.
