Motorola ReFLEX Transceiver
Figure 11 shows a block diagram of the Motorola ReFLEX
chipset solution including the AD6140. As can be seen, the
AD6140 accepts an IF input from a crystal filter at 49.6 MHz.
The frequency synthesizer provides the 6.144 MHz clock, while
the LO is also generated from the frequency synthesizer but is
fed to the AD6140 via the I/Q modulator. The IF data output
and the clock output both feed into the IF data processor. The
LNA bias amplifier provides the AGC voltage for the first LNA
in the receive path. The dc power is supplied from the power
management chip.
