DATA SHEET 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 m 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 s carrier lifetime of these diodes results in resistance of 100 maximum at 1 mA and 10 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 (SMP1307-027LF) is a diode array designed for four-diode Pi attenuator circuits. Table 1 describes the various packages and marking of the SMP1307 series.
