The 3H Industries SW2-20 is a Single Pole Double Throw (SPDT) RF switch engineered for wideband applications spanning DC to 20 GHz. It delivers the frequency agility and signal routing control required in test, measurement, and communication systems. With SMA connectors and 50 Ohm impedance, it integrates directly into standard RF architectures.
Technical Specifications
• Switch Type: RF Switch, SPDT configuration
• Frequency Range: DC to 20 GHz
• Impedance: 50 Ohms
• Connectors: SMA (SubMiniature version A)
– Key Features
The SPDT topology allows routing of a single input signal to either of two output paths—essential for antenna selection, source switching, and signal path management in RF systems. DC-coupled operation extends utility across ultra-low frequencies and DC conditions. The 50 Ohm characteristic impedance ensures impedance matching with industry-standard RF equipment and transmission line systems.
– Typical Applications
Suitable for antenna selection networks, test signal distribution, receiver/transmitter switching, filter bank configuration, and multipath signal routing in instrumentation and communications test benches. Applicable across microwave frequencies up to 20 GHz and compatible with pulsed and continuous-wave RF signals.
– Compatibility & Integration
SMA connectors provide mechanical and electrical compatibility with standard RF test equipment, signal generators, spectrum analyzers, and network analyzers. The 50 Ohm system impedance aligns with common transmission line standards and passive RF component ecosystems.
