R = ----------
f step
f ref = reference oscillator frequency (e.g. 10.25 MHz)
f VCO = VCO frequency
f rec = reception frequency
f step = step frequency (of the PLL)
10. Diagrams
The following data was measured with the application board (see Figure 10-9 ).
In the measurement setup, a 50 Ω generator is terminated by 50 Ω and connected to the antenna
input by a 50 Ω series resistor to achieve 75 Ω termination at the antenna input. The generator
level specified is the output voltage of this 50 Ω generator at 50 Ω load. If the application board is
replaced by a 75 Ω resistor, the voltage at this resistor is 6 dB below the specified voltage level of
the 50 Ω generator.
