The output frequency is controlled by applying a variable tune voltage to the VTUNE port. Because VTUNE is varied from the lowest to the highest allowed voltage, the VCO output frequency increases from the lowest to the highest operating frequency. This VCO output frequency change with the applied VTUNE input results in the VCO frequency sensitivity characteristic (MHz/V). The VCO frequency sensitivity is not constant and varies across the tunable range. The HMC1168 VCO is specified to cover the minimum to maximum frequencies specified in this data sheet over the entire specified temperature range, including the VCO frequency drift (MHz/°C). In addition, for low phase noise operation, drive the VTUNE port from a low noise voltage source. Excessive noise on the VTUNE port results in poor phase noise performance. The tune port modulation bandwidth is typically greater than 10 MHz. To achieve optimum VCO phase noise performance when using the HMC1168, it is important to use a low noise power supply for VCC biasing. Because the VCO output frequency changes with small changes in the VCC bias voltage (pushing), noise on the VCC bias pin results in increased phase noise. Take care to use low noise regulators, otherwise, bias line noise may corrupt the low phase noise output of the HMC1168. Internally, the radio frequency (RF) output frequency is generated from a doubler circuit. This generation results in an unwanted low level output signal present at half the RFOUT frequency (RFOUT/2). If necessary, this undesired spurious signal can be further filtered on the customer application board using a filter. The RFOUT/2 output signal is available directly at the RFOUT/2 port. The RFOUT/2 port commonly drives a phase-locked loop (PLL)/synthesizer for phase locking the HMC1168 output if needed. Lastly, the HMC1168 RFOUT port incorporates an internal buffer amplifier to provide good output matching. The internal buffer amplifier also isolates the VCO core from the output load and minimizes the VCO frequency change with the changes to the output load impedance (pulling). Rev.

The primary applications are point to point microwave radios, military, radars, test and measurement, as well as industrial and medical equipment. The low phase noise allows higher orders of modulation and offers improved bit error rates in communication systems, whereas the linear, monotonic tuning sensitivity allows a stable loop filter design. The higher output power minimizes the gain required to drive subsequent stages. The half frequency output reduces the input frequency to the prescaler without the addition of residual phase noise to the input of the phase-locked loop synthesizer.
