PSPL5544 Datasheet

The PSPL5544 is an ultra-broadband, high-current, coaxial bias insertion tee and DC blocking capacitor. The high DC blocking voltage (100 V) and high bias current capability (2 A) make it an excellent choice for broadband measurements of power devices and circuits.

Key performance specifications
  • 50 kHz to 40 GHz
  • 8 ps rise time
  • 100 V, 2 A

Typical performance

The following figures show the linear sweep from 40 MHz to 50 GHz. The AC connector is the input (port 1) and the AC + DC connector is the output (port 2).

The following figure shows the S21 insertion loss.


The following figure shows the S11 return loss.


The following figure shows the S22 return loss.
