MS-156 Series
NEWNEW
2003.11
■Features
1. Low insertion loss
0.1 dB typical at 6 GHz (not mated with the plug).
2. Space-saving design
2.7 mm x 2.7 mm occupied board space.
3. Low profile
1.6 mm protrusion above the board.
4. Lightweight
0.025 g. total weight (without vacuum cap).
5. Durability
100 mating/unmating cycles, with corresponding plug.
6.
Performs over a wide frequency range
Applicable frequencies range over a wide band,
from DC to 6 GHz.
7.
Board placement with automatic equipment
Packaged on tape-and-reel. Also available with a
vacuum cap over each switch.
8.
Supports lead-free environments
All components use lead-free materials.
■Applications
Portable terminals, ETC, notebook computers (Bluetooth),
wireless LAN, POS terminals, GPS terminals, PDA, and any
small devices requiring verification of antenna/circuit
performance.
■Overview
Developed for inspection of high frequency
circuits used in portable terminals.Verification of
the circuit performance is
accomplished by simply
inserting the external plug
in the board mounted
receptacle.This action re-directs the circuit from
normal condition to the plug side. Removing the
plug restores circuit to its normal condition.
