Coaxial RF Switches
Route RF signals with electromechanical or PIN diode control.
Specify topology, band, RF power, switching speed, control interface and the unselected-port condition for the selected switch.
- ✓ SPDT, DPDT and multi-throw electromechanical switches
- ✓ Absorptive and reflective PIN diode switches
- ✓ Failsafe, latching and TTL options by model
Route RF Signals Through Electromechanical or Solid-State Switching Paths
Select switch technology from the required topology, frequency, RF power and switching speed. Specify the control interface and unselected-port condition.
Low insertion loss and high isolation coaxial relay architectures up to 50 GHz.
SP3T to SP12T configurations enabling compact automated multi-channel test matrices.
Solid-state nanosecond-speed switching in absorptive and reflective configurations up to 40 GHz.
Switch Types
- Electromechanical SPDT and DPDT: Classic transfer switches with highest RF isolation.
- Electromechanical multi-throw: SP3T up to SP12T in radial and compact barrel geometries.
- PIN diode absorptive switches: Terminated 50Ω state in unselected ports for low VSWR.
- PIN diode reflective switches: Low insertion loss solid-state switching for high power paths.
Features & Advantages
- Electromechanical configurations to 50 GHz: SMA, 2.92mm and 2.4mm interfaces.
- Actuator options: Failsafe, latching, and normally-open coil architectures (12V & 24V DC).
- PIN designs with nanosecond switching: Fast electronic switching speeds down to 40 ns.
- TTL control options: Integrated TTL driver logic for straightforward micro-controller integration.
