Table 28. Bill of materials for the application circuit

Note: Shaded items are different for different frequencies

Note that the component values for 868

and 915 MHz can be the same. However,

it is important that the layout is optimised

for the selected VCO inductor in order to

centre the tuning range around the

operating

frequency

account

for

inductor tolerance. The VCO inductor must

be placed very close and symmetrical with

respect to the pins (L1 and L2).

Chipcon provides reference layouts that

should be followed very closely in order to

achieve

the

best

performance.

The

reference design can be downloaded from

the Chipcon website.
