The SD3464 is an inner DC block from 10 MHz to 18 GHz with N connectors, manufactured by Fairview Microwave for RF and microwave applications. It features a frequency range of 0.01 to 18 GHz with 50 Ohm impedance, a maximum VSWR of 1.35:1, and insertion loss not exceeding 0.6 dB, ensuring minimal signal degradation. The device is rated for a maximum operating DC voltage of 200 Volts and operates reliably across a temperature range of -65°C to +125°C. The connectorized design includes an N Male connector on one end and an N Female connector on the other, both constructed with beryllium copper and gold plating for superior conductivity and corrosion resistance. The housing is made of passivated stainless steel, providing durability and environmental protection. This DC block is ideal for RF systems requiring DC isolation while maintaining high-frequency signal integrity in instrumentation, test equipment, and communication systems.
