Surface Mount PIN Diode
SP2T Switches
MSW2040-204 & MSW2041-204
Series Datasheet
Description
The MSW2040-204 and MSW2041-204 Series of Surface Mount Silicon PIN Diode SP2T Switches is
manufactured using Aeroflex/Metelics proven hybrid manufacturing process incorporating High Voltage
PIN Diodes and passive devices integrated within a ceramic substrate. This low profile, compact, surface
mount component, ( 8mm L x 5mm W x 2.5 mm H ) offers superior low and high signal performance to
comparable MMIC devices in QFN packages. The SP2T switches are designed in a symmetrical topology
to optimize Insertion Loss and Isolation performance.
Using PIN Diodes with lower thermal resistance ( < 10 C/W ), RF C.W. incident power levels of +50 dBm
and RF peak incident power levels of +57 dBm are very achievable in higher power cold and hot switching
applications @ +85 C. The lower PIN Diode series resistance ( < 1.0
Ω ), coupled with the longer minority
carrier lifetime, ( > 2 μS ), provides better IIP3 distortion values > +65 dBm.
Applications
These MSW2040-204 and MSW2041-204 Series SP2T Switches are designed to be used in higher power
switch applications, operating from 20 MHz to 4000 MHz, requiring high volume, surface mount, solder
re-flow manufacturing. These products are durable, reliable, and capable of meeting all military,
commercial, and industrial environments. The devices are fully RoHS compliant.
Environmental Capabilities
The MSW2040-204 and MSW2041-204 Series SP2T Switches are capable of meeting the environmental
requirements of MIL-STD-202 and MIL-STD-750.
ESD and Moisture Sensitivity Level Rating
PIN Diode Switches are susceptible to ESD conditions as with all semiconductors. The ESD rating for this
device is Class 1C, HBM. The moisture sensitivity level rating for this device is MSL 2.
