SPDT High Isolation CATV Switch 5 - 1000 MHz V1 MASWSS0068 MASWSS0068 Features • • • • • • Functional Schematic 75 Ohm Impedance Positive Voltage Control (0 / +5 V) Low Insertion Loss: 0.60 dB at 870 MHz High Isolation: 51 dB at 870 MHz 4 mm FQFP-N 20 Lead Package 0.5 micron GaAs PHEMT Process GT1 GND GT2 GND GND RF1 RF2 Description GND GND M/A-COM’s MASWSS0068 is a GaAs PHEMT MMIC single pole double throw (SPDT) switch in a low cost 4 mm FQFP-N 20 lead package. The MASWSS0068 is ideally suited for applications where low control voltage, low insertion loss, high isolation, small size and low cost are required. Typical applications are to replace mechanical relays in CATV systems. This part can be used in all 75 ohm systems operating up to 1.0 GHz. GND GND GND GND The MASWSS0068 is fabricated using a 0.5 micron gate length GaAs PHEMT process. The process features full passivation for performance and reliability.
