The RMT-II Dual Band transmitter comprises six main modules or assemblies:
1.
Motherboard.
This board accommodates the digital encoder and modulator boards,
as well as providing DC, signal and I
2
C communications routing to/from all other
modules.
2.
Encoder module.
This module accepts all signals provided for digital transmission
and uses MPEG2 encoding / multiplexing techniques to produce a digital transport
stream for the modulator module.
3.
Modulator module.
This module accepts the digital transport stream from the
encoder module and uses digital COFDM modulation techniques to produce a digital
RF signal at the required RF frequency.
4.
Power Amplifier.
This module accepts the analog or digital RF signal at a level of –
10dBm (nominal) and amplifies the signal to a level of 500 mW (+27dBm) nominal.
5
Power amplifier control PCB
. This PCB accepts DC inputs from the PSU and
controls the operation condition of the Output Power Amplifier (not fitted to 2 GHz
systems).
6.
Front panel module.
This module contains a microprocessor plus six push buttons
and an LCD display for overall monitoring and control of the RMT-II Dual Band
transmitter.
