5 CIRCUIT DESCRIPTION AND SCHEMATIC DIAGRAMS T2130
The analog switch U15/2 which is controlled by the microprocessor via the serial device bus and the shift
register U14 and the driver U09/3 switches between the AE-current and the Vforward.
AE-current comes in from the AT2110 to the TX-processor in P05, pin 3 and is divided by the resistors
R42 and R44. When the level exceeds approx. 5.7 Volt the diode D20 opens and the dividing ratio is
changed. This ensures that the level corresponds to the logarithmic scale on the RE2100.
Vforward comes in from the Output Filter (3) at P04, pin 7 and is divided by the resistors R49 and R44.
The selected signal is buffered by U06/2. The output is fed to P05, pin 8 and runs to the processor unit
(8) in the RE2100 where it is conditioned and lead to the display unit (7) in the RE2100 where it is mixed
with the AGC-signal from the Receiver (1). Please refer to the circuit description for the RE2100 modules.
