DC to 6GHz Ultra-Small Coaxial Switch
MS-147 Series
ꢀOutline
The ultra-small MS-147 coaxial switch series
was developed for the portable terminal interface
and for inspection of microwave boards (sub-
strates) (DC – 6GHz) used at high frequencies.
To respond to the development of portable
terminal technologies and popularization of high-
frequency applications – up to 6GHz – this
switch features low loss, low profile, and light
weight.
The switch circuit is designed so that the NC
terminal is connected to the C terminal without a
plug mated. Mating with a plug opens this
connection.
Vertical mounting structure allows the switch to
be placed near the antenna of the portable
terminal and used to inspect output and switch to
an external antenna.
ꢀFeatures
Saves board mounting space:
Low profile: Height 3.9mm
Light weight: Weight 0.11g
01. Low insertion loss
Insertion loss is as low as:
0.15dB(or less)(Typically, 0.08dB at 1GHz)
(Typically, 0.1dB at 2GHz)
02. Space saving
External dimensions are 5.8mm x 5.4mm. Saves installation
space.
03. Low profile
Switch height is 3.9mm.

operations.
06. Auto insertable
Available in embossey tape-and-reel auto-insertable
format
07. Wide application range
Operating frequency from DC to 6GHz.
08. Prevention of flux float-off
