Product description

Additionally to the analog modulation voltage a digital modulation control signal can switch on and off the RF power. Both the analog and digital modulation are characterized by extraordinary on/off ratios of at least 65dB.

The driver can be operated with modulation frequencies (analog and digital) up to 25% of the carrier frequency and 50 MHz maximum.

Optimum EMC shielding and mechanical protection are achieved by an aluminum casing. The base plate serves for mounting as well as for heat dissipation.

Key features

  • Constant output power design
  • Models with a modulation frequency up to 50 MHz available
  • Conductive cooling through base plate
  • Compact casing, fully shielded (EMC)
