| SW-277 High Power GaAs SPDT Switch DC - 2.0 GHz Features * * * * * * Positive Supply and Control Voltages 1 dB Compression Point: +36 dBm Typical, 8 V 3rd Order Intercept Point: +65 dBm Typical, 8 V Low Insertion Loss: 0.4 dB Typical Low Power Consumption: 100 W Fast Switching Speed Rev. V6 Functional Schematic Description M/A-COM's SW-277 is a GaAs MMIC SPDT switch in a SOIC-8 lead surface mount plastic package. The SW-277 is ideally suited for use where low power consumption is required. Typical applications include transmit/receive switching, switch matrices and switched filter banks in systems such as radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment. The SW-277 is fabricated using a monolithic GaAs MMIC using a mature 1 micron process. The process features full chip passivation for increased performance and reliability.
