4.4 Crystal Frequency Calculation
The local oscillator (UHF PLL) signal has to be high-side injected into the down-
converting mixer. Thus the crystal frequency is calculated by using the following
formula:
QU
= (
RF
+ 10.7) / r
with

local oscillator (PLL) frequency (

....
....
ratio of local oscillator (PLL) frequency and crystal
frequency as shown in the subsequent table.
This yields the following example:
