Figure 11: RF Frequency Block Plan
Due to the AMPS mode, simultaneous reception and transmission, TX and RX IF frequen-
cies are exactly 45 MHz apart. RXIF is 135.54 MHz and TXIF is 180.54 MHz. The RXIF fre-
quency is set so that it is not a multiple of either of VHF's comparison frequency (120k).
In digital mode (TDMA800), RXIF frequency is 135.54 MHz and TXIF is (180.54MHz).

Note: The current values in the following figure are not absolute values and cannot be measured.
These values represent maximum/typical currents drawn by the corresponding RF or Taco blocks in
use, and are, therefore, dependent on the phone’s operating mode and state.
