Mixer pole selection. Set 1 to program the passive filter pole at mixer output at 36MHz, or
set 0 to program the pole at 13MHz.
LNA mode selection, D14:D13 = 00: LNA selection gated by the antenna bias circuit, 01:
LNA2 is active; 10: LNA1 is active; 11: both LNA1 and LNA2 are off.
Mixer enable. Set 1 to enable the mixer and 0 to shut down the mixer.
Antenna bias enable. Set 1 to enable the antenna bias and 0 to shut down the antenna bias.
IF center frequency programming. Default for f CENTER = 3.092MHz, BW = 2.5MHz. The
MSB of FCEN is located in Register Test Mode 2 (Table 16).
001101 = 3.092MHz, 001011 = 4.092MHz, 010011 = 10.0MHz
