Market Trends For Low Cost High Performance VCO Solutions
By Ulrich L. Rohde and Ajay k. Poddar, Synergy Microwave Corp.
Communication systems rely on low-phase-noise signal sources such as tunable oscillators or phase-lock-loop (PLL) synthesizers for reliable voice communications and to ensure transmitted data integrity. Constraints on cost, size, power-efficiency, performances are particularly demanding. The need for a miniaturized configurable wideband Voltage-controlled oscillator (VCO) solution has been a dream for decades. With ever-increasing demands for highspeed data communications at rates in excess of 2 Gb/s, the phase-noise performance of the miniaturized tunable VCO becomes critical in achieving acceptable system bit-error-rate (BER) performance. Fortunately, a design approach based on the patented technology1-8 has been used to develop a line of high-performance; compact VCOs that offer performance levels well suited to the demanding requirements of existing and emerging wireless communications systems.
