Specifications & What's Included

  • Model: 70MDF-DAT-GLW; Manufacturer: 3dbm, Inc.
  • Includes: WV Communications FM Modulator (70-01FM-CH), FM Demodulator (70-01FD-CH), 3dbm RF Attenuator (50AT-1-2R)
  • RF Input Frequency: 69.6 MHz / 70.0 MHz selectable
  • Power: 115 VAC, 1-phase, 47–63 Hz, 1A fuse
  • Connectors: BNC (RF/tone), DB-9, IEC AC inlet
  • Status indicators: AC PWR ON (green LED), FAULT (red LED) per module

Applications

FM modulators and demodulators are core components in satellite ground station equipment for uplink and downlink signal processing. This unit is typical of systems used in fixed satellite service (FSS) and other telecom infrastructure where RF signal conversion and attenuation are required. WV Communications modules are established in professional ground station installations.

Condition: Used
This 3dbm 70MDF-DAT-GLW FM Modulator Rackmount Unit with WV Communications modules has been inspected and is in good used condition. It was pulled from a working satcom environment where it was actively in use and functional. The chassis and front panels show light surface wear consistent with normal rack service life, but the unit is clean overall with no significant damage. All three modules — the WV Communications FM modulator (70-01FM-CH), FM demodulator (70-01FD-CH), and 3dbm RF attenuator (50AT-1-2R) — are present and installed. Please view our photo set and contact us if you have any questions.
