| RoHS Compliant GaAs Transfer Switch, DC-3.0 GHz Features * * * * * * * Small Ceramic Package, 0.250" Sq. Fast Switching Speed, 4 ns Typical Ultra Low DC Power Consumption 50 Ohm Nominal Impedance MIL-STD-883 screening available Lead-Free CR-4 Package 260C Reflow Compatible SW-283-PIN V4 Functional Block Diagram GND GND GND GND RF1 GND GND RF2 RF4 GND GND RF3 Description M/A-COM's SW-283-PIN is a GaAs MMIC transfer switch packaged in lead-free, surface mount CR-4 ceramic style packages. SW-283-PIN offers low insertion loss, high isolation, and fast switching. This ceramic switch platform has a common footprint for all three designs. The CR-4 package is hermetically sealed, making this switch 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. The SW-283-PIN transfer switch contains a monolithic GaAs MMIC which is fabricated using a 1.0 micron MESFET process.
