Key Features
- Bidirectional Operation: The RF input signal can be applied to the RFC port while the RF throw port (RF1 or RF2) is output or vice versa.
- Internally Matched: The component is internally matched to 50 Ω at the RF common port (RFC) and the RF throw ports (RF1 and RF2), eliminating the need for external matching components.
- CMOS/LVTTL Logic-Compatible Control: The switch features dual digital control input pins (CTRL and EN) that are compatible with CMOS/LVTTL logic.
- Dual Supply Voltages: Requires +3.3 V and -2.5 V supply voltages.
- High Isolation and Low Insertion Loss: Optimized for high-frequency applications with excellent isolation and low insertion loss characteristics.
Applications
- Broadband and Satellite Communications: Suitable for use in high-frequency, high-performance communication systems.
- Microwave Radios: Used in microwave radio systems due to its high-frequency capabilities.
- Very Small Aperture Terminals (VSATs): Ideal for VSAT applications requiring reliable and high-performance RF switching).
