SP3T Datasheet, PDF (1/1 Pages) List of Unclassifed Manufacturers – PIN Diode Switches 0.5 to 18.0GHz Non-Reflective

SP3T PIN Diode Switches
0.5 to 18.0GHz
Non-Reflective
Features:
• Removable SMA Connectors
• Integral TTL Compatible Drivers
• Internally Terminated
• Miniature Outline
• Very Fast Switching
• Low Loss and
High Isolation
Description:
The SMS-331-00DT range of SP3T PIN diode
switches are packaged in miniature, silver
plated housings with SMA connectors. The
SMA connectors can be removed to allow direct integration into microstrip circuits if required and all units
contain TTL compatible drivers. Ports J2, J3 and J4 are internally terminated to maintain VSWR when the
switch is isolating. Optional surface finish is available, see note below for options.

Notes:
1. Power supplies: +5V @ 100mA max, -5V @ 50mA max.
2. Total switching time is defined as 50% TTL to 10/90% detected RF.
3. 3 Individual TTL compatible control lines are provided. TTL ‘0’ = low loss, TTL’1’ = isolation.
4. TTL Control Voltage should be = or < positive supply voltage at all times.
5. Operating temperature range –40° to +85° C. Storage temperature range –55° to +125° C.
6. Third angle projection, all dimensions in mm.
7. Port J1 = RF common , Port J2 = RF input/output, Port J3 = RF input/output, Port J4 = RF input/output.
8. Options:
Add the following identifiers as suffixes to the part numbers above, i.e. SMS -331-01DTP.
P = Finish Matt black paint to DTD5555A.
The switch is available without integral drivers to allow users to externally optimise bias levels. Please consult the factory for detail
information.
Please contact the factory for any custom requirements or applications assistance.
