VCO frequency characteristic
VCO frequency
with extra
offset
PC1, PC2
With R1 and R2 within the ranges 3 k
< R1 < 300 k, 3 k< R2 < 300 k,
the characteristics of the VCO operation will be as shown in Fig. 24.
Fig. 24 Frequency characteristic of VCO operating with offset:
fo = centre frequency; 2fL = frequency lock range.
Selection of R1, R2 and C1
PC1, PC2
Given f0 and fL, determine the value of product R1C1 by using Fig.29.
Calculate foff from the equation foff =fo 1.6fL.
Obtain the values of C1 and R2 by using Fig.28.
Calculate the value of R1 from the value of C1 and the product R1C1.
