The SD3467 is an inner DC block designed to prevent the flow of DC current while allowing RF signals to pass. It operates over a frequency range of 10 MHz to 4 GHz with a maximum insertion loss of 0.5 dB and a maximum VSWR of 1.35:1. This 50 Ohm component can handle a DC operating voltage up to 200 Volts and is configured with a BNC male to BNC female interface. With a wide operating temperature range from -65°C to +125°C, the SD3467 is suitable for various applications in test and measurement, telecommunications, and RF systems requiring DC signal isolation.
