Description .0099-0.0196 x 45° Chamfer (0.25-0.50) .010(0.25) M C A M B S M/A-COM’s SW-337, SW-338 and SW-339 are GaAs MMIC SPDT terminated switches in a low cost SOIC 8-lead surface mount plastic package. They are ideally suited for use where very low power consumption is required. Typical applications include transmit/receive switching, switch matrices, and filter banks in systems such as: radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment. The difference between the switches is in the pin configuration. 8-Lead SOP outline dimensions Narrow body .150 (All dimensions per JEDEC No. MS-012-AA, Issue C) Dimensions in ( ) are in mm.
