Current Settings are SPI controllable
Freescale’s IP3 boost circuitry
Bypass mode included for improved intercept point performance
Total supply current:
LB – 9.7 mA in current setting 6
HB1 – 9.2 mA in current setting 6
HB2 – 6.5 mA in current setting 2
10 µA (typical) in bypass mode
Bias stabilized for device and temperature variations
QFN-16 leadless package with low parasitics
SiGe technology ensures lowest possible noise figure
SPI controlled
At POR, all bands default to bypass mode. In deep sleep mode, all bands are set to disable mode.
