The detailed functional description is given in the following sections. Figure 20:RF Block Diagram Frequency Synthesizers The VCO frequency is locked by a PLL (phase locked loop) into a stable frequency source given by a VCTCXO, which is running at 26 MHz.
RM-8/RM-47/RM-48 7 - System Module Nokia Customer Care The loop filter filters out the comparison pulses of the phase detector and generates a DC control voltage to the VCO. The loop filter determines the step response of the PLL (settling time) and contributes to the stability of the loop. The frequency synthesizer is integrated in Helgo except for the VCTCXO, VCO, and the loop filter. Receiver Each receiver path is a direct conversion linear receiver.
