Abstract :
This paper looks into the audio gain line-up of TETRA 800 MHz radios. The focus is on the design of each gain block in both transmit and receive audio paths. It should be noted that the designs described in this paper are implemented based on DIMETRA-PTM system requirements and recommendations provided by ETSI. In addition, transducer characterizations were taken into consideration in implementing the audio gain line-up that we see today.
