DATA SHEET SMP1304 Series: Low-Distortion Attenuator Plastic Packaged PIN Diodes Applications TV distribution Attenuator circuits Features Low-distortion design Frequency range from 5 MHz to >2 GHz Designed for base station applications Configured for PI and TEE attenuators Packages rated MSL1 260 C per JEDEC J-STD-020 Description The SMP1304 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 100 m I region of these PIN diodes makes them very attractive for use in low-distortion PI and TEE attenuators commonly found in TV distribution applications. The 1 s typical carrier lifetime of these diodes results in a resistance of 20 maximum at 1 mA and 7 maximum at 10 mA. The SMP1304 series is available in a selection of plastic packages: as a single diode in small footprint SOD-323 and SC-79 packages, and in a variety of configurations in an SOT-23 package, including the low inductance (0.4 nH) SMP1304-007. The SMP1304-019, a three-diode junction designed for insertion in PI attenuators, is available in an SOT-143 package. The SMP1304-027 is available in an SOT-5 package as 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 SMP1304 series. Skyworks Solutions, Inc.

SMP1304-007 insertion in PI attenuator circuits in common use from 10 MHz to >1 GHz. The SMP1304-019 PIN diode junction was designed for The inductance of the SMP1304-007 is effectively reduced to low capacitance, a wide resistance dynamic range, and low 0.4 nH compared to the 1.5 nH of the standard configuration. The distortion performance. lower inductance is particularly beneficial when the diodes are used as shunt-connected switches at frequencies >500 MHz where inductance is the primary limitation on maximum switch Electrical and Mechanical Specifications isolation. The absolute maximum ratings of the SMP1304 series are To achieve the effective 0.4 nH, the SMP1304-007 must be provided in Table 2. Electrical specifications are provided in inserted in the microstrip circuit board with a gap in the trace as Table 3. Resistance versus temperature measurements are shown in Figure 1. Because of the polarity of the diode junction, provided in Table 4. the low inductance can only be achieved with the cathode Typical performance characteristics of the SMP1304 series are connected to ground. illustrated in Figures 3 to 6. Package dimensions are shown in Figures 7 to 15 (odd numbers), and tape and reel dimensions are provided in Figures 8 to 16 (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 Figure 1. SOT-23 Package Trace Gap when the part is subjected to high temperature during solder assembly. The SMP1304 series is rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. It can be used for lead or lead-free soldering.
