More about DC Blocks
A DC Block is a coaxial component that prevents the flow of DC current into the RF Signal path, thereby minimizing interference. There are three main types:
- Inner DC Blocks: Have a capacitor in series with the center conductor.
- Outer DC Block: Have a capacitor in series with the outer conductor.
- Inner/Outer DC Block: Have a capacitor in series with both the inner and outer dc block.
Frequency (MHz): The frequency up to which the device can effectively block out the DC signal from the RF Signal path.
Breakdown Voltage (V): This is the voltage beyond which the device ceases to operate.
Impedance: The impedance of the dc block is matched to the circuit impedance to prevent any reflections. 50 Ohms and 75 Ohms are the two most common options.
Power Rating (W): This is the level of power that the dc block can handle.
everything RF lists DC Blocks from multiple manufacturers and lets you search for them using a parametric search tool. You can view specs, download datasheets and request quotations on products the meet your requirement.
