PSPL5500 Series DC Blocks

PSPL5500A, PSPL5501A, PSPL5508 Datasheet

The PSPL5500 Series of DC Blocks is composed of extremely broadband, coaxial blocking capacitors. Due to the coaxial construction, excellent microwave and very fast rise time responses are achieved. The PSPL5508 has a -3 dB bandwidth in excess of 26 GHz and a rise time faster than 8 ps. Large capacitance values up to 2.2 μF are available that give -3 dB low frequency cutoffs as low as 0.7 kHz.
