VCOs (Voltage Controlled Oscillators)
Voltage Controlled Oscillators (VCOs) are voltage-dependent electronic circuit components based on LC, crystal, and hybrid technologies. They enable control of the oscillation frequency by varying an externally applied voltage.
The UMZ-351-A16-G is a hybrid CMOS VCO designed for use in commercial and industrial applications. This VCO offers excellent RF performance with a wide frequency range of 3.7 to 4.5 GHz. It also provides high linearity and low phase noise levels over its operating range.
Application field and Working Principle
The UMZ-351-A16-G is designed to be used in various fields such as Wi-Fi, WiMAX, and low-cost Point-to-Point links. Its wide frequency range makes it suitable for a wide range of applications, from Wi-Fi networks to point-to-point communications systems. It can also be used in communication links where higher perturbations are expected.
The UMZ-351-A16-G operates based on a unique design which includes both a voltage-controlled oscillator (VCO) and a phase-locked loop (PLL). The VCO has two inputs: a tuning voltage and an input from a frequency synthesizer. The VCO is internally tuned by the voltage-controlled oscillator to generate a signal of a specified frequency at its output. The phase-locked loop utilizes theoutput of the VCO to adjust its internal frequency. This enables the PLL to obtain the exact frequency required by the system.
Also, the VCO has an active pull-in range, which is determined by the magnitude and shape of the voltage tuning curve. The pull-in range of the PLL is also determined by the shape of the VCO tuning curve. These two parameters are important for system frequency stability.
The UMZ-351-A16-G also integrates a low noise amplifier (LNA) which provides a wide dynamic range and excellent linearity. This allows for accurate signal detection and rejection of interfering signals. In addition, the VCO features an integrated band-pass filter with low residual noise which eliminates out-of-band noise to ensure high-precision transmission.
In conclusion, the UMZ-351-A16-G is a high-performance VCO that combines the advantages of both VCO and PLL technology. It is suitable for applications such as Wi-Fi, WiMAX, and other communication systems requiring wide frequency ranges and good performance in the presence of interfering signals and perturbations.
