SMP1307-027 Four-Diode PI Attenuator

The SMP1307-027 uses four PIN diode junctions in a five-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 over 1 GHz.

A broadband attenuator was designed using the SMP1307-027

that shows good performance up to 2 GHz. The attenuator was

evaluated with a 50

Ω source and load impedance. Figure 1

shows a block diagram and circuit diagram for this device (the

typical performance of the SMP1307-027 is shown in Figure 2).

Electrical and Mechanical Specifications

The absolute maximum ratings of the SMP1307 series are

provided in Table 2. Electrical specifications are provided in

Table 3. Resistance versus temperature measurements are

provided in Table 4.

Typical performance characteristics of the SMP1307 series are

illustrated in Figures 2 to 6. Package dimensions are shown in

Figures 7 to 11 (odd numbers), and tape and reel dimensions are

provided in Figures 8 to 12 (even numbers).
