The PSPL5547 is a broadband, coaxial bias insertion tee and DC blocking capacitor. It was designed to have a very low cutoff frequency of only 5 kHz. It passes fast rise pulses with a minimum of waveform distortion. Its rise time is 23 ps. The frequency response is very flat, and the -3 dB bandwidth extends from 5 kHz to 15 GHz. The PSPL5547 is supplied with a 1 mH choke and terminal strip for connection to the DC bias.

1A 1 mH choke is supplied with the bias tee. It is to be wired in series directly to the DC in solder terminal on the coax module. This is a high impedance point. Avoid using long wire, especially coax, for this connection. Do not locate the choke close to ground. Excessive stray capacitance will cause a resonance that will appear as a dip in the insertion loss between 1 and 10 MHz
