The Model 5331 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 W input impedance when both outputs are terminated in 50
W. Power Divider tees are built using three 16.7 W resistors and thus present a 50 W 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 W. It has a risetime of 17 ps and bandwidth from DC to >18 GHz.
