| RoHS Compliant GaAs SPDT Switch DC - 4 GHz Features * Terminated (SW-226-PIN), High Isolation (SW-227-PIN), Low Loss (SW-228-PIN) * Fast Switching Speed: 6 nS Typical * Ultra Low DC Power Consumption * Lead-Free 7-Lead Ceramic Package * RoHS* Compliant and 260C Reflow Compatible SW-226/227/228-PIN V5 Block Diagram/Pin Configuration SW-226-PIN 3 RF Common 50 50 Description M/A-COM's SW-226/227/228-PIN are GaAs MMIC SPDT switches packaged in lead-free, surface mount CR-2 ceramic style packages. The SW-226PIN is a terminated SPDT. The SW-227-PIN offers high isolation. The SW-228-PIN offers low insertion loss. This ceramic switch platform has a common footprint for all three designs. The CR-2 package is hermetically sealed, making these switches ideal for space, military radios, and other environmentally harsh applications. Typical applications include synthesizer switching, transmit/receive switching, switch matrices and filter banks in systems such as radio and cellular equipment, PCM, GPS, and fiber optic modules.
