| SW-475 SPDT High Isolation Terminated Switch 0.5 - 3.0 GHz Features * Positive Voltage Control (0 / +5 V) * High Isolation (53 dB typ. @ 0.9 GHz, 50 dB typ @ 1.9 GHz) * 50-Ohm Internal Terminations * Low Insertion Loss (0.6 dB typ. @ 0.9 GHz, 0.7 dB typ. @ 1.9 GHz) * 4 mm 16-Lead PQFN Package Rev. V6 Functional Schematic 16 15 14 13 RF2 1 2 3 4 V1 V2 5 6 7 8 RFC RF1 12 11 10 9 Description The M/A-COM SW-475 GaAs monolithic switch provides high isolation in a low-cost, plastic surface mount package. The SW-475 is ideal for applications across a broad range of frequencies including synthesizer switching, transmit / receive switching, switch matrices and filter banks in systems such as radio and cellular equipment, PCS, GPS, and fiber optic modules. M/A-COM fabricates the SW-475 using a 1.0-micron gate length MESFET process. The process features full chip passivation for performance and reliability.
