Low Distortion Attenuator
Plastic Packaged PIN Diodes
Features
s Low Distortion Design
s Frequency Range from HF to > 2 GHz
s Designed for Base Station Applications
s Configured for PI and TEE Attenuators
SMP1304 Series
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.
