PSPL5372 Datasheet

The PSPL5372 Z-Matched Pick-off Tee is an ultra-broadband resistive device that provides a scaled 5x (14 dB) pick-off of the input signal. The PSPL5372 exhibits excellent through-line impedance match to 50 ohms for frequencies from DC to 26 GHz, unlike conventional 14 dB pick-off tees that have DC resistance of 42 ohms at the input. The PSPL5372 features outstanding insertion loss and group delay flatness. Either Port 1 or Port 2 may be used as the input.

Key performance specifications
  • Excellent Through-Line Impedance Match
  • Minimizes Signal Reflections
  • DC to 26 GHz
  • 5x (14 dB) Pick-off
