Description
The MSW3200-320 and MSW3201-320 Surface Mount Silicon PIN Diode SP3T Switches are
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, (8 mm L x 8 mm W x 2.5 mm H) offers superior low and high signal performance to
comparable MMIC devices in QFN packages. The SP3Tswitches are designed in a symmetrical topology
to optimize Insertion Loss and Isolation performance.
Using PIN Diodes with lower thermal resistance (< 10 ºC/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 ºC. The lower PIN Diode series resistance (< 1.0
Ω),
coupled with the longer
minority carrier lifetime, ( > 4 μS ), provides better IIP3 distortion values > + 65 dBm.
Applications
These MSW3200-320 & MSW3201-320 SP3T Switches are designed to be used in higher power switch
applications, operating from 20 MHz to 1,000 MHz, and 400-4,000 MHz respectively for high volume,
surface mount, solder re-flow manufacturing useful in IED and Radar market segments. These products
are durable, reliable, and capable of meeting all military, commercial, and industrial environments. The
devices are fully RoHS compliant.
Environmental Capabilities
The MSW3200-320 and MSW3201-320 SP3T Switches are capable of meeting the environmental
requirements of MIL-STD-202 and MIL-STD-750.
ESDand 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.

Electrical Specification Notes:
1. Switching Speed (50 % TTL – 10/90 % RF Voltage) is a Function of the PIN Diode Driver Performance.
A RC “ Current Spiking Network” is used on the Driver output to provide a Ic = C dV/dt transient current
to move Stored charge through the PIN Diode, typical values are: R = 50 – 220
Ω
and C = 470 – 1,000 pF.
2. Aeroflex / Metelics MPD3T5N200-703 is the recommended Driver to interface with the MSW3200-320 and
MSW3201-320 SP3T Switches and its data sheet may be found at http://www.aeroflex.com/metelics.
3. PIN Diode D.C. Reverse Voltage to maintain High Resistance in the OFF PIN diode is determined by RF
Frequency, Incident Power, and VSWR. The Minimum D.C. Reverse Voltage values are provided on page 5
of this datasheet. -5 V @ -50 mA values may be utilized for small signal testing ~0 dBm.
