OUTPUT MATCHING
There are a number of ways to match the output of the
ADF4360-8 for optimum operation; the most basic is to use a
50 resistor to VVCO. A dc bypass capacitor of 100 pF is
connected in series, as shown in Figure 27. Because the resistor
is not frequency dependent, this provides a good broadband
match. The output power in the circuit below typically gives
9 dBm output power into a 50 load.

Figure 27. Simple ADF4360-8 Output Stage
A better solution is to use a shunt inductor (acting as an RF
choke) to VVCO. This gives a better match and, therefore, more
output power.
Experiments have shown that the circuit shown in Figure 28
provides an excellent match to 50 over the operating range of
the ADF4360-8. This gives approximately 0 dBm output power
across the specific frequency range of the ADF4360-8 using the
recommended shunt inductor, followed by a 100 pF dc blocking
capacitor.

The recommended value of this inductor changes with the VCO
center frequency. A graph of the optimum inductor value vs.
frequency is shown in Figure 29.

Both complementary architectures can be examined using the
EVAL-ADF4360-8EB1 evaluation board. If the user does not
need the differential outputs available on the ADF4360-8, the
user should either terminate the unused output or combine
both outputs using a balun. Alternatively, instead of the LC
balun, both outputs may be combined using a 180° rat-race
coupler.
