3. TECHNICAL BRIEF
3.5.9.1 RBR1000
The RBR1000 CMOS RFIC is a highly integrated receiver IC ideally suited for FLO multicast reception
in the 698 to 746 MHz frequency range. In the United States, this corresponds to TV channels 52 to 59
in the UHF band. It uses radioOne® technology that implements directconversions from RF-
tobaseband, completely eliminating the receiver intermediate frequency to reduce component count
and space. The RBR1000's high level of integration simplifies handset designs while saving DC power
and board space
CU920 uses only LNA1_INPUT(channel 55 and main frequency 719Mhz)
only CU920
