MS-145-C(LP)-1

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. Frequency range Can be used from DC to 2.5 GHz and with GSM, PCS, cdmaOne,W-CDMA, etc. 02. Low profile Low protrusion of only 6mm above the mounting surface (receptacle). 03. Durability High durability(mating/unmating) of 10 000 cycles. 04. Self alignment of mating parts Inducement to floating is ±0.5mm. 05. Light weight Plug Weight is only 0.18g. 06. Small board surface solder area The area is 7 ∞4.6mm(excluding leads). 07. Automatic mounting Receptacle designed for placement on board with automated equipment. 08. Solder wicking Receptacle terminations are designed to prevent solder wicking into the critical contact areas. MS-145-C(LP)-1 MS-145-C(LP)-A MS-145-HRMJ MS-145-HRMP 09. Plugs Wide variety of mating heights are available. 10. Adaptors Different adaptors are available. ■Applications Mobile Phone antenna switching Checks of microwave boards, etc. ■Materials Part Material Outer shell Phosphor bronze Insulator Polyamide resin Common contact Beryllium copper Board circuit side (N.C.) contact Beryllium copper Color/Finish UL standard --------------- UL94HB Mounting area : Solder over Nickel plating --------------- Contact area : Gold over Nickel plating --------------- Others : Nickel Plating --------------- --------------- Gold plating Mounting area : Solder over Nickel plating --------------- Contact area : Gold over Nickel plating --------------- Others : Nickel Plating --------------- 113 ■Performance Specification Operating temperature range -30ç to +85ç Power 2 W (4W : at 1/8 duty ratio) Frequency range DC to 2.5 GHz 0.3 dB or less (DC to 1 GHz) Insertion loss 0.4 dB or less (1 GHz to 2 GHz) 0.6 dB or less (2 GHz to 2.5 GHz) 20 dB or greater (DC to 1 GHz) Isolation 15 dB or greater (1 GHz to 2 GHz) 12 dB or greater (2 GHz to 2.5 GHz) 1.3 or less (DC to 2 GHz) V.S.W.R. 1.5 or less (2 GHz to 2.5 GHz) Item Requirement Test Condition 1.
