PSPL5331 6 dB Power Divider, 18 GHz Datasheet

PSPL5331 Datasheet

The PSPL5331 6 dB Power Divider is a very broadband, resistive tee. It is useful for splitting a signal into two identical signals or for combining two signals. The output is attenuated by 6 dB. These are impedance-matched tees that present a 50 Ω input impedance when both outputs are terminated in 50 Ω. Power Divider tees are built using three 16.7 Ω resistors and thus present a 50 Ω impedance at any port. The resistors in this tee have 1% tolerances and thus this tee has excellent symmetry and very close impedance match to 50 Ω. It has a rise time of 17 ps and bandwidth from DC to >18 GHz.

Typical performance

Frequency responses from 40 MHz to 20 GHz, linear sweep at 2 GHz/div
