The UMZ-875-D16-G is part of a family of voltage controlled oscillators (VCOs), which are widely used to control frequency, phase, or timing in many areas of electronics, including communication systems, test and measurement equipment and alarm systems. The UMZ-875-D16-G is a specifically designed VCO for use in broadcast radio and television applications. As such, it is characterized by its high performance, low RF and noise levels and low power consumption.

VCOs offer a unique way of controlling frequency, and as such, they are essential building blocks in many electronic applications, from basic digital and clock oscillators to more complex frequency synthesizers and multi-channel digital communications systems. At the heart of any VCO is a tuning element or resonator. This can be a crystal, a quartz or a ceramic resonator, or an electrostatic capacitive or inductive resonator, depending on the type of VCO. The frequency of an VCO is directly controlled by an external voltage, usually in the range of 0.5 to 8 V. This voltage induces a corresponding change in the frequency of the oscillator.

For the UMZ-875-D16-G, the resonator is a ceramic resonator, which is a temperature stable and reliable solution that obviates the need for a temperature compensating circuit. The ceramic resonator also provides the best frequency stability and low phase noise performance over its operating temperature range (-20 to +85°C). It has a frequency range of 16 MHz to 4 GHz and tuning range of 1.5 to 4 GHz. It has a typical tuning sensitivity of 0.08 GHz/V, a typical minimum VCO gain of 50 dBc/Hz and a low phase noise of -120 dBc/Hz at 1 GHz.

The UMZ-875-D16-G has a very low inband noise and excellent dynamic parameters, with a typical tuning speed of 14µs and a settling time of 5ms. It also supports an input voltage range of 1.5 to 8 V, and a typical current consumption of 5mA. The VCO is packaged in a small, standard package size, making it easy to use in both commercial and military applications. It has a high power handling capability (>100W), and a wide tuning range that can meet the stringent requirements of broadcast applications.

The UMZ-875-D16-G is thus an excellent choice for use in broadcast radio or television applications, or any other applications requiring reliable, high performance VCOs with wide tuning range and low power consumption. It can be used to control frequency, phase or timing in a variety of systems, from basic digital and clock oscillators to more complex multi-channel digital communications systems.
