A voltage-controlled oscillator chip (VCO chip) is an oscillator integrated circuit whose output frequency is tuned by an external control voltage. It typically consists of an oscillation core, a resonant network, varactor diodes/variable capacitors, a buffer amplifier, a bias circuit, and a temperature compensation circuit. It features a wide frequency range, good tuning linearity, low phase noise, stable output power, good harmonic suppression, fast tuning speed, small size, and high reliability. The product covers microwave/millimeter-wave frequency bands and meets the requirements of different quality grades of national military standards (GJB) and various application platform environments. It is widely used in frequency sources, phase-locked loops (PLLs), frequency synthesizers, radar, communications, electronic countermeasures, satellite communications, test and measurement, and phased-array systems. Based on Si, SiGe, GaAs, GaN, CMOS and other process platforms, the company can provide customized VCO chip solutions according to customer needs.
