2.3.3 P.A. card
The TETRA vehicular amplifier is housed on the solder side of the R/T card near
the dissipation fins. The P.A. card amplifies the RF input signal coming from the
R/T card in order to supply a power output of 40 dBm in the vehicular radio
operating frequency range (the operating frequency range is different according to
the VS 2001 different versions: see Tab. 1.2). The RF signal amplification is
obtained via a line that consists of a bipolar technology transistor polarised in class
AB, driven by an LDMOS technology power module.
