INTRODUCTION
VMD
The VMD (Video Microwave Digital) Series of compact, low power consumption transmitters
provide exceptional video quality in high multipath environments. They are ideal for use inside
buildings, in urban areas, and in other applications where multipath would normally cause video
tearing or breakup.
All VMD Series transmitters offer three bandwidth modes: DVB-T (6, 7, 8 MHz), Narrow (2.5
MHz), and Ultra Narrow (1.25 MHz) channel spacing. All modes transmit video, two channels of
voice, and data. VMD transmitters may be located on adjacent channels without a guard band.
AES 128-bit (256-bit optional) encryption ensures users of secure communications.
The VMD 100 is a small transmitter with a choice of high or low RF output power level,
selectable in software, and each user-selectable up to 100 mW. This unit is ideal for
concealments, and shorter range robotic and UAV applications. The package is only 2.50” x
1.88” x 0.44” (approximate dimensions not including connectors).
Power consumption is less than 4.5 Watts (low power setting) or less than 5.0 Watts (high
power setting). Operation time on a fresh set of Lithium batteries is more than eight hours*.
All connections are conveniently located off the ends of the unit. The VMD can be
conveniently powered by standard AA batteries.
