TOP PREVIOUS NEXT
The RF section consists of two main components: The PMB6610 transceiver and the PMB6618 power
amp.
In the transceiver the 10.368MHz clock signal SYCL is multiplied to around 1.9GHz using PLL (Phase
Locked Loop) control. The TXDA signal is used to control the modulation of this frequency to 1.87GHz
to 1.93GHz.
Received signals are demodulated, filtered and sent to the BBIC via the RXDA line.
