PSPL5340 Datasheet

The PSPL5340 is a broadband, resistive, Pick-Off, Power Divider Tee. The pick-off port 3 output is a small replica of the signal passing through the tee. The PSPL5340 is an impedance-matched tee consisting of three precision, 1% tolerance resistors. The PSPL5340 input/output impedance seen either on port 1 or port 2 is precisely 50 Ω.

Mechanical dimensions

1 All parameters listed are typical unless max/min guaranteed limits are provided. Using the pick-off tee for input signals with rise times faster than 80 ps is not recommended. This tee can be used with faster rise times, but there will be waveform distortions. With faster rise times, either the thru-line bandwidth is insufficient and/or the pick-off output will no longer be a faithful representation of the input signal. The pick-off output rise time will be too fast and there will be some overshoot and ringing.
