RoHS Compliant GaAs SPDT Switch DC - 4 GHz SW-226/227/228-PIN V5 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 260°C Reflow Compatible Block Diagram/Pin Configuration SW-226-PIN 3 RF Common 50 50 Description RF1 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. RF2 A1 B1 B2 A2 Block Diagram/Pin Configuration SW-227-PIN 3 RF Common 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. RF1 RF2 The SW-226/227/228-PIN are fabricated as monolithic GaAs MMICs using a 1.0 micron MESFET process.
