SMP1307-027 4 Diode PI Attenuator
The SMP1307-027 employs 4 PIN diode junctions in a
5-lead SOT package. It is configured for ease of
insertion in the PI attenuator circuit commonly used for
broadband TV distribution systems, covering a frequency
range from 5 MHz to beyond 1 GHz.
A broadband attenuator was designed using the
SMP1307-027 showing good performance to 2 GHz. The
attenuator was evaluated with a 50
source and load
impedance. The following figure shows the circuit
diagram and measured performance.
