Technical Description
The SKY73120-11 is a fully integrated VCO that includes
varactors, a band select module, oscillator, output buffer, and RF
balun. The output power from the RF balun is 0 dBm and the
output impedance is designed to be 50 Ω.
The band select module can be used to change the center
operation frequency of the VCO by controlling the BS1 and BS0

pin signals. This allows the total frequency range to be extended
by keeping the same Kv and phase noise performance. The
control logic for the BS1 and BS0 pins is shown in Table 2 and
illustrated in Figure 3.
The band select pins BS0 and BS1 contain 10 kΩ pull-up
resistors.
