Rev 0.0 and to suppress the DAC image and the DAC spurious. The output power is programmable. A power detector (PD_out) on the radio IC enables close-loop TX power control. The differential RF PA outputs are connected via a baluns and Diplexer to a transmit/receive switch with TX diversity option to the RF connectors. 5. Clock and synthesizer frequencies The main crystal is connected to the Baseband IC crystal oscillator. This in turn buffers this 44MHz and feeds it to the radio IC.
