MS-147

DC to 6GHz Ultra-Small Coaxial Switch MS-147 Series sOutline The ultra-small MS-147 coaxial switch series was developed for the portable terminal interface and for inspection of microwave boards (substrates) (DC – 6GHz) used at high frequencies. To respond to the development of portable terminal technologies and popularization of highfrequency 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. sFeatures 01. Low insertion loss Insertion loss is as low as: 0.15dB(or less)(Typically, 0.08dB at 1GHz) (Typically, 0.1dB at 2GHz) Saves board mounting space: Low profile: Height 3.9mm Light weight: Weight 0.11g 02. Space saving External dimensions are 5.8mm x 5.4mm. Saves installation space. 03. Low profile Switch height is 3.9mm. MS-147(06) 04. Light weight Switch weight is 0.11g 05. Long life The switch is guaranteed for up to 12,000 mechanical operations. qPlug 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 Switch structure prevents flux float-off. MS-147-C(LP)-1 09. Self-alignment The eccentricity for plug mating is ±0.5mm. qSMA conversion adapter sApplication * Wireless communication (Bluetooth, IEEE 802.11) * Machines (Portable terminal, notebook PC, ETC, POS terminal, GPS terminal PDA, etc.) * Also suitable for other high-frequency machines.
