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:

Key Specifications

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 has created the largest database of DC Blocks, with over 300 DC Blocks listed from more than 30 manufacturers. All the data has been standardized across the manufacturers so that you can search for DC Blocks by Type, Frequency, Breakdown Voltage, Insertion Loss and other parameters. Once you find a list of DC blocks that meet your requirement, you can see product details, download the datasheet, compare products or request a quotation. All quotations for DC Blocks requested via everything RF will be directed to the manufacturer or their distributor who will get back to you with the details.
