The operating current in the VCO core is programmable in four
steps: 5 mA, 10 mA, 15 mA, and 20 mA. This is controlled by
Bits PC1 and PC2 in the control latch.
OUTPUT STAGE
The RF
nected to the collectors of an NPN differential pair driven by
buffered outputs of the VCO, as shown in Figure 15. To allow
the user to optimize the power dissipation vs. the output power
requirements, the tail current of the differential pair is pro-
grammable via Bits PL1 and PL2 in the control latch. Four
current levels may be set: +3.5 mA, +5 mA, +7.5 mA, and
+11 mA. These levels give output power levels of −13 dBm,
−11 dBm, −8.5 dBm, and −6.5 dBm, respectively, using a 50 Ω
resistor to V
both outputs can be combined in a 1 + 1:1 transformer or a 180°
microstrip coupler (see the Output Matching section).

If the outputs are used individually, the optimum output stage
consists of a shunt inductor to V
Another feature of the ADF4360 family is that the supply current
to the RF output stage is shut down until the part achieves lock as
measured by the digital lock detect circuitry. This is enabled by the
mute-till-lock detect (MTLD) bit in the control latch.
