Very Low Distortion Attenuator Plastic Packaged PIN Diodes: SMP1307 Series
Skyworks offers the SMP1307 Series of plastic packaged, surface mountable, low capacitance silicon PIN diodes designed for attenuator applications operating from 5 MHz to beyond 2 GHz. With a thick 175 μm I region width, these PIN diodes are ideal 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. A diode array designed for four-diode Pi attenuator circuits is also available in an SOT-5 package.
