Description

The SMP1304 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes are designed for use in attenuator applications from 5 MHz to beyond 2 GHz.The thick 100 µm I region of these PIN diodes makes them very attractive for use in low distortion PI and TEE attenuators commonly used in TV distribution applications. The 1 µS typical carrier lifetime of these diodes results in resistance of 20 Ω maximum at 1 mA and 7 Ω maximum at 10 mA. 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, including a low inductance (0.4 nH) SMP1304-007 package. Also available in the SOT -143 package are three diode junctions designed for insertion in TEE attenuators (SMP1304-018) and PI attenuators (SMP1304-019). Also available in a SOT -5 (SMP1304-027) package as a four diode array designed for insertion in the commonly used 4 diode PI attenuator circuit.

Low Distortion Attenuator Plastic Packaged PIN Diodes SMP1304 Series Alpha Industries, Inc.[781] 935-5150 • Fax [617] 824-4579• Emailsales@alphaind.com • www.alphaind.com 3 Specifications subject to change without notice. 1/01A SMP1304-019 (PI) SMP1304-007 In the -007 configuration of the SOT -23 package, the package inductance is effectively reduced to 0.4 nH, in comparison to the 1.5 nH value of the standard configuration. This lower inductance will be particularly beneficial when the diodes are used as shunt connected switches at frequencies higher than 500 MHz, where inductance is the primary limitation on maximum switch isolation. To achieve the effective 0.4 nH, the SOT -23 package must be inserted in the microstrip circuit board with a gap in the trace, as shown in the figure. Because of the polarity of the diode junction, this low inductance feature is only realizable with the cathode connected to ground. SMP1304-019 PI Attenuator PIN Diodes The SMP1304-019 employ three PIN diode junctions in a SOT -143 package. They are configured for ease of insertion in PI attenuator circuits commonly used from 10 MHz to beyond 1 GHz.The SMP1304 PIN diode junction was designed for low capacitance, wide resistance dynamic range and low distortion performance.
