Digital MMDS and BRS Series Transmitters LSI -50D and LSI -100D

The Loma Scientific International "D" Series transmitters enablewireless cable TV operators to broadcast DVB-C digital QAMchannels over large geographical areas economically, by multplexingvarious MPEG programs in a single RF licensed channel whilemaintaining digital video quality. For example, at 5:1 compression itis possible to deliver 155 digital programs in an MMDS market that

used to carry only 31 analogprograms. The "D" series transmitters are perfect for single channelEBS/BRS FCC Part 27-M systems and can easily be adapted formultichannel systems with a single transmitter.

Standard Features include:

! High reliability design with straightforward operation and easy setup! Class A linear power amplification providing very low ACPR! Modular components in a space saving compact chassis! Wideband block upconversion simplifies channel selection! Backward compatible with combined carrier analog modulators [1]! Capable of multichannel operation at reduced power per channel [2]! Front panel RF (SMA) test point and forward/reverse power meter
