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 evalu-
ated with a 50 Ω source and load impedance. The following
figure shows the circuit diagram and measured performance.
