LOCAL OSCILLATOR FOR WCDMA RECEIVER
Figure 33 shows the ADF4208 used to generate the local
oscillator frequencies for a wideband CDMA (WCDMA)
system.
The required RF output range is 1720 MHz to 1780 MHz. The
VCO190-1750T meets this requirement. Channel spacing is
200 kHz with a 20 kHz loop bandwidth. VCO sensitivity is
32 MHz/V. A charge pump current of 4.375 mA is used and the
desired phase margin for the loop is 45°.
When the IF output is fixed at 200 MHz, the VCO190-200T is
used. It has a sensitivity of 10 MHz/V. Channel spacing and
loop bandwidth are chosen to be the same as the RF side.
