The SD3235 is an inner DC block with SMA connectors that blocks unwanted DC signals while allowing AC drive signals to pass through across a frequency range of 7 kHz to 23 GHz. It features a blocking capacitor on the inner conductor, 50 Ohm impedance, and a maximum insertion loss of 1 dB, with a VSWR of 1.4:1 and maximum operating voltage of 100 Vdc. The device is housed in passivated stainless steel with beryllium copper gold-plated connectors (SMA Male to SMA Female), measures 0.87 inches in length and 0.312 inches in width, and operates reliably across a temperature range of -65°C to +125°C with a maximum input power of 2 Watts. Common applications include test and measurement, ground loop elimination, and signal-to-noise ratio improvement in RF and microwave systems.
