RH-17 System Module CCS Technical Documentation Transmitter Figure 6: Trimode block diagram The transmit chain up to the RF driver stage is integrated into one transmit-integrated circuit called Robin, with external power amplifiers (PA). The channel spacing is 50 kHz. All data transmitted on the channel is convolutionally encoded and block-interleaved.

In order to save energy in puncture mode, when there is no speech activity during a call, the driver and power amplifiers and the Robin IC are switched ON and OFF rapidly. These units also are in the OFF state when the transmitter is in standby. The ON/OFF switch commands are issued by a Digital ASIC (UPP).
