Radyne DMD20 Universal Satellite Modem

Description

The Radyne DMD20 Universal Satellite Modem breaks new ground in flexibility, operation and cost. The Radyne DMD20 Universal Satellite Modem standards including IDR, IBS and DVB, and covering data rates up to 20 Mbps, this 1RU duplex modem covers virtually all your Satellite IP, Telecom, Video and Internet applications.

The Radyne DMD20 Universal Satellite Modem can switch between spur-free 70/140 MHz operation and L-Band without any configuration changes as both interfaces are active similtaniously.

The Radyne DMD20 Universal Satellite Modem now offers DoubleTalk® Carrier-in-Carrier® bandwidth compression, based on patented “Adaptive Cancellation” technology, allows transmit and receive carriers of a duplex link to share the same transponder space. DoubleTalk Carrier-in-Carrier is complementary to all advances in modem technology, including advanced FEC and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier utilising advanced signal processing techniques provides a new dimension in bandwidth and power efficiency.

The extensive list of software options allows for budgeting the modem for today’s needs while covering tomorrow’s plans. These options can be purchased and then activated in seconds via the front panel.
