Interface Coaxial Switches MS-145 Series ■Overview and applications Designed primarily as interface coaxial switch for a mobile phones, they are also used in variety of other applications requiring redirecting of signals when mating with corresponding plug. The mating action redirects the signals from the receptacle side to the plug side. Receptacle ■Features 01. Space saving External dimensions are 7mm x 4.6mm. Saves installation space. 02. Low profile Low protrusion of only 6mm above the mounting surface (receptacle). 03. Light weight Weight is only 0.18g. 04. Durability High durability(mating/unmating) of 10 000 cycles. 05. Automatic mounting Plug Receptacle designed for placement on board with automated equipment. 06. Frequency range Can be used from DC to 2.5 GHz and with GSM, PCS, cdmaOne,W-CDMA, etc. 07. Plugs Wide variety of mating heights are available. 08. Solder wicking MS-145-C(LP)-1 MS-145-C(LP)-A MS-145-HRMJ MS-145-HRMP Receptacle terminations are designed to prevent solder wicking into the critical contact areas. 09. Self alignment of mating parts Inducement to floating is ±0.5mm. ■Applications Mobile Phone antenna switching Checks of microwave boards, etc. ■Materials Part Material Outer shell Phosphor bronze Insulator Polyamide Common contact Beryllium copper Board circuit side (N.C.) contact Beryllium copper Finish Remarks --------------- UL94HB --------------- Gold plating Mounting area : Solder plating --------------- Contact area --------------- : Gold plating Mounting area : Solder plating --------------- Contact area --------------- : Gold plating 111 ■Product Specifications Operating temperature range -30ç to +85ç Power 2W Frequency range DC to 2.5 GHz Insertion loss 0.4 dB Max.
