Analog Video Distribution Amplifier

The IQVDA02/03 provides up to 14 equalized analog video outputs. It is an ideal budget distribution amplifier for analog video applications. Maintenance of video quality is ensured by the 35 MHz frequency response. The equalizer ensures flat response (±0.1 dB) to 15 MHz necessary for quality distribution.


  • Up to 14 high-quality outputs
  • Balanced loop-through input
  • Terminating input option allows extra output
  • 35 MHz bandwidth
  • Equalizer, better than ±0.1 dB to 15 MHz with 100 m RG59 cable
