R573F03440

Overview

The R573F03440 is a general purpose SP4T coaxial RF switch manufactured by Radiall USA, Inc. It operates within a frequency range of 0 to 26.5 GHz and maintains a 50 Ohm impedance. The device requires a 28V DC supply voltage for actuation. It features a normally open configuration with TTL diode control logic. The component utilizes SMA connectors and includes a D-sub connector interface for control signals.

Feature Summary

• SP4T coaxial switching architecture
• Operates up to 26.5 GHz frequency
• Normally open state configuration
• TTL diode control logic integration

Applications

• RF signal routing in test equipment
• Telecommunications base station systems
