RF Switching Unit
Dual drive exciter system
RF Switching Unit is a key component to design Dual drive Terrestrial transmitters. It is fully interoperable with Twister II and Vortex II exciter platform to build secured DVB-T/T2, ATSC1.0/3.0, ISDB-T/TB and DTMB broadcast systems.
Highlights
Fast switching
The RF Switching units, control by dry contact, switch from RF input 1 to RF input 2 in less than 100 ms.
Autonomous or Manual
Many monitoring events detected inside exciters can be used to control the RF Switch. A manual switching is also possible for maintenance operation.
Power Amplifier Control
Specific power Off / power On cycle time can be configured according your power amplifier characteristics.
Double PSU
RF Switching unit is equipped with a double power supply for a better security.
