DC-Blocks up to 110 GHz for High-Frequency Signal Isolation
DC-Blocks are essential components in RF and microwave systems, providing reliable isolation between circuit stages while maintaining signal integrity across broad frequency ranges. These components block unwanted DC voltage while allowing AC signals to pass through unimpeded, protecting sensitive receiver front-ends, amplifier circuits, and measurement instrumentation at millimeter-wave frequencies.
The DC-Blocks featured here extend coverage up to 110 GHz, delivering high-performance isolation solutions for demanding telecommunications, satellite, defense, and research applications.
