PRO-DAR

Receiver Multicoupler family with redundant amplifier system for the VHF & the low UHF range 30 – 960 MHz.
Description
  • Active Receiver multicouplers PRO-DAR (Dual Amplifier RMC) comes with 1 antenna input and 4 or 8 receiver outputs. The PRO-DAR’s with 12 or 16 outputs are under development.
  • Allows a number of receivers to share the same antenna without interaction and loss of signal.
  • Coves the whole frequency range 30 to 960 MHz.
  • If only a smaller frequency range is desired, a preselector filter can be built in to prevent possible interference from strong transmitters outside the frequency band of interest. Amphenol Procom offer a wide range of both band selective and narrow-band low-loss filters suitable for preselector use.
  • Please refer to the preselector overview and specify frequency range when ordering.
  • The build-in ultra-high dynamic range amplifiers ensure outstanding multicoupler linearity and high reject of distortion products.
  • Low amplifier noise figure ensures lowest possible S/N deterioration of the received and distributed RF signals.
  • Redundant amplifier design with two identical amplifier stages coupled in parallel ensures maximum operational reliability.
  • If a fault occurs in one amplifier stage,the amplifier will continue to operate with gain around -6 dB relative to the normal gain providing uninterrupted service with only minor performance deterioration.
  • High isolation between receiver outputs ensure insignificant low mutual coupling between the connected receivers.
  • Operates on 230 V AC or 115 V AC mains supply or 12 V, 24 V or 48 V DC supply (Depending on type, see ordeing designations)
  • Galvanically isolated power supply with floating power supply input prevents unwanted ground loops and ensures operation on DC voltage systems with both + and – to ground.
  • Power supply backup function provides automatic switching to DC supply if the AC mains supply fails, ensuring uninterrupted service of the multicoupler.
  • POWER ON/operating status LED on front.
  • Supply voltage/current monitoring alarm circuitry with floating relay switch-over alarm contact. If a fault occurs, in the RF amplifer circuitry, the alarm circuitry immediately toggles the relay to indicate fault condition and change the POWER on/operating status LED from constant green light to flashing red light.
  • If both mains AC supply and DC supply fail, the multicoupler is completely de-energized, the relay will also be toggled to indicate fault condition. The POWER ON / operating status LED will then be off in this situation.
  • Mains supply connector: IEC type fitted with noise filter.
  • DC power supply connector: Pluggable terminal block/header fitted with noise filter.
  • Alarm connector: Pluggable terminal block/header.
  • RF connectors: N-female on all ports (other types on request).
  • Comes as standard with black powder lacquered front plate
  • 19” rack module housing
  • PRO-DAR4 & PRO-DAR8: 1HU
  • PRO-DAR12 & PRO-DAR16: 2HU (Under development)
  • Please Note:
  • Power cable is not included. Must be ordered separately, see Accessories.
