| RoHS Compliant High Power GaAs SPDT Switch DC - 3.0 GHz Features * * * * * * * 1 dB Compression Point: +39 dBm @ -8 V 3rd Order Intercept: +65 dBm @ -8 V Insertion Loss: 0.4 dB Low Power Consumption Fast Switching Speed Lead-Free High Performance Ceramic Package RoHS* Compliant and 260C Reflow Compatible SW-276 V3 Functional Schematic/Pin Configuration Description M/A-COM's SW-276 is a broadband GaAs SPDT switch available in a lead-free, 7-lead ceramic package. The 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. M/A-COM fabricates the SW-276 using a 1.0-micron gate length MESFET process. The process features full chip passivation for performance and reliability.

Table B Screening 2. Table 1 Screening 3. Exceeding any one or combination of these limits may cause permanent damage to this device. 4. M/A-COM does not recommend sustained operation near these survivability limits. 5. TCASE = +25C, where TCASE is the temperature at the bottom of the case. 6. Special consideration must be given to the mounting of the switch to minimize the thermal resistance. The bottom of the case should be thermally attached to the mounting surface to maintain the junction temperature under the absolute maximum rating. * Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
