473 to 4A3 Series INTELLIGENT RELAY SP7T & SP10T IN-LINE Multithrow Switches Available with either CMOS Binary logic decoding circuits or MOSFET pulse latching electronics, these DowKey INTELLIGENT RELAY Multithrow Switches were designed to simplify the physical construction and reduce the amount of supporting (logic and switch driver) electronics required to implement complex switch assemblies. These SP7T and SP10T DowKey INTELLIGENT RELAY IN-LINE Multithrow Switches are ideal for complex switch matrix or test equipment applications. Typical applications for the 473-4A3 Series include: • Test Equipment Band Selection • Switch Matrixes RF Characteristics Frequency GHz VSWR (max) Isolation dB (min) 0-2 2-8 8-12 12-18 1.50 1.50 1.50 2.00 80 70 65 60 DowKey® 473 to 4A3 Series INTELLIGENT RELAY SP7T & SP10T IN-LINE Ins.
