SMP1307 Series: Very Low Distortion Attenuator Plastic
Packaged PIN Diodes
Applications
Very low distortion PI and TEE attenuators
Cable TV AGC
High-volume wireless systems
Features
Low distortion design
Frequency range from 5 MHz to > 2 GHz
Packages rated MSL1 @ 260 °C per JEDEC J-STD-020
Description
The SMP1307 series of plastic packaged, surface mountable, low
capacitance (0.3 pF) silicon PIN diodes is designed for attenuator
applications from 5 MHz to beyond 2 GHz.
The thick 175 μm I region width of these PIN diodes makes them
very attractive for use in very low distortion PI and TEE attenuators
commonly found in TV distribution applications. The 1.5 μs carrier
lifetime of these diodes results in resistance of 100 Ω maximum
at 1 mA and 10 Ω maximum at 10 mA.
The SMP1307 series is available in a selection of plastic
packages, as a single diode in the small footprint SOD-323
package, and in a variety of configurations in the SOT-23
package. Also available in an SOT-5 package (SMP1307-027) is a
four-diode array designed for insertion in commonly used four-
diode PI attenuator circuits. Table 1 describes the various
packages and marking of the SMP1307 series.

Figure 1. SMP1307-027 Block Diagram and Schematic
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).

Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
The SMP1307 series is rated to Moisture Sensitivity Level 1
(MSL1) at 260 °C. It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.

Note: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
