This paper starts with a remind of the main performances of the transmitter which is able to modulate data up to 50 Mbps (up to 100Mbps with technical restriction), deliver 2 Watts with no more than 10W DC/DC consumption in only 0.3U dimensions. Then, the architecture of the transmitter is presented with all the key functions such as the power amplifier, synthesizer, IQ modulator, filters. Some results achieved on the prototype are presented with particular attention to the consumption, BER measurements and transmitter quality losses. The process used to select and qualify the key components is also described. |
