Description

Fairview Microwave’s SD8218A is an inner and outer DC block with BNC connectors. It has a blocking capacitor on the inner and outer conductor and operates from 100 MHz to 4 GHz. Our BNC DC block offers good insertion loss of 0.5 dB and has a maximum operating voltage of 200 Vdc. DC blocks are commonly used to filter out unwanted DC signals, while allowing AC drive signals to pass through. They can help improve signal to noise ratio (SNR), eliminate ground loops, or provide isolation in your test setup. All of Fairview Microwave’s DC blocks are in stock and available to ship same-day.
