2.2 Block Diagram Description
2.2.1 General
Figure 2-2 describes the block diagram of the Miltel Galaxy Pit2 Transmitter. This
device consists of two major sections, all using a common power source:
¾ Digital section (Micro Controller)
¾ RF section
A 3.6 volts Lithium battery provides power to all parts of the device. The power
supply for the RF section is controlled via the Tx switch (not shown), thus cutting of
power to the transmitter unless necessary for actual data transmission (standby mode).
