VCOs (Voltage Controlled Oscillators)

Voltage Controlled Oscillators (VCOs) are electronic devices used to create a range of frequencies depending on an external voltage source. They use feedback to generate an electrical signal at a specific frequency, usually around an output frequency range. VCOs are used in many electronic and radio frequency (RF) applications, such as phase-locked-loops, signal generators, and mobile radios.The UMX-270-D16-G is a low cost, high accuracy low phase noise VCO designed for use in ultra-wideband (UWB) and ISM bandwidth applications. The VCO operates with a supply voltage of 3.3V and delivers an output signal ranging between 2.7GHz and 3.5GHz. The device offers excellent phase noise performance with low phase noise of -92dBc/Hz at 1MHz offset. The phase noise is further improved by the use of high Q ceramic resonator for the oscillator system. With optimized phase noise and good frequency stability, the UMX-270-D16-G is an ideal choice for various UWB and ISM applications, including point-to-point and point-to-multipoint millimeter-wave communications.The UMX-270-D16-G is a wideband, voltage-controlled oscillator (VCO) device with a range of digital tuning pins to control the frequency and phase of the output signal. The digital tuning control is enabled through the input port. The device includes a low noise buffer amplifier and a VCO amplifier. The device has a low noise output buffer amplifier which provides low noise performance as well as a high linearity to the output signal. The VCO amplifier’s gain is adjustable through the external capacitors, enabling the user to adjust the VCO gain over a large range; from -180dB to -260dB.The UMX-270-D16-G has an optimized low frequency control system, allowing for large and rapid frequency changes. The low frequency control system is enabled through an internal control loop and external resistors. By modifying the external resistors, the user can achieve various frequency control settings. Also, the device has a wide tuning voltage range from 0.8V to 2.6V. This allows for precise control of frequency and phase.The UMX-270-D16-G has an integrated low-Q power-down mode which provides a low power consumption with a surprisingly low noise level. The low-Q mode provides a low quality factor (Q) on the output. This allows the device to be powered down while still providing the benefit of low noise performance.In summary, the UMX-270-D16-G is a highly integrated voltage-controlled oscillator device suitable for ultra-wideband RF applications. Its transmission bandwidth, low noise performance, low power consumption, wide tuning voltage range, and low-Q power-down mode make it an ideal choice for UWB use cases. Its excellent phase noise performance, adjustable gain, and low frequency control system enable precise and rapid frequency changes for a wide range of UWB applications.
