Radiall RF Coaxial Switch R574F93405

The R574F93405 is an RF switch from Quarktwin Technology Ltd., designed for applications requiring a 4-way switch configuration. It operates across a frequency range of 0 to 26.5 GHz with a characteristic impedance of 50 Ohms. The switch features a maximum insertion loss of 0.20 dB at DC - 3 GHz, increasing to 0.70 dB at 18-26.5 GHz, and provides a minimum isolation of 80 dB for optimal signal integrity. This model supports an average power handling capability of up to 240 W at 25¬8C, with a termination average power rating of 1 W per termination. The actuator is latching, requiring a nominal current of 250 mA and operates at a voltage of 28V (with a range of 24 to 30V). The switch is equipped with a 25-pin D-SUB male connector and SMA female connectors per MIL-C 39012 standards. Mechanical durability is notable, with a lifespan of 3 million cycles per position and a switching time of less than 40 ms. The device is splashproof and operates within a temperature range of -40¬8C to +85¬8C, making it suitable for various environmental conditions.
