MODE SELECT LOGIC AND DC CHARACTERISTICS
The SA9503 chip has several modes of operation for which the selection logic is defined in the following two tables. Different mode selections
require different portions of the circuit to be active. Modes from unlisted combinations of logic pins, are not valid. Total current consumption of
the device is the sum of the currents for the mixer portion (Table 2) and the LNA portion (Table 3).
