15 GHz Bias Tee

PSPL5580 Datasheet

The PSPL5580 is a broadband coaxial bias insertion tee and DC blocking capacitor designed to pass fast rise pulses without waveform distortion. The rise time is 28 ps with a –3 dB bandwidth extending from 10 KHz to 15 GHz. The PSPL5580 is designed to handle DC currents up to 2 A. The PSPL5580 is supplied with an external choke mounted to a terminal strip and an additional inductive circuit on an external PCBA.

¹ The PSPL5580 consists of a coaxial unit, external coil and a separate pc board. These are hi-z circuits. To prevent undesired HF resonances, do not use coax or long wires. If the pc board is not used, the low frequency cut-off is 500 kHz.
