The impedance of the second-order loop filter is shown as ZLPF. The VCO conversion gain, KVCO, represents the sensitivity of VCO frequency with tuning voltage in rad/(s Â V). 00 fref KPFD Iout(s) 192 198 204 210 KVCO /s ZLPF(s) fbck C1 Vcont(s) fout C2 R1 ÷N Prescaler ÷P fout /P Fig. 8 Simplified s-domain representation of the synthesizer ratio of the prescaler and lower frequency divider chain is represented by P and N, respectively. 4) which shows a pole at the origin due to the VCO. The over-all loop dynamics are determined by the transfer-function of the loop-filter, which in this case is an 24 2 Synthesizer System Architecture impedance function, as it converts the charge-pump current to a tuning voltage for the VCO.

Signal connections, no matter how carefully made, are not perfect at mm-wave frequencies. The small dimensions contribute to signal loss which typically rises with frequency. In case of coaxial cables, impedance and insertion loss varies with different cable routing. Furthermore, bending and stretching cables changes their dimensions, and thus affects signal propagation. This is particularly critical when measuring phase sensitive circuits (I-Q VCOs, phase shifters etc) where matching is of utmost importance.
