By Hittite Microwave Corporation
Integration, performance and functionality, are three of the most common requests made by RF & Microwave designers striving for leading edge systems with components that can help them deliver that often elusive market edge. In the world of signal generation, Hittite Microwave Corporation is meeting these challenges with the introduction of broadband Frequency Synthesizers and Phase Locked Loop (PLL) integrated circuits which are designed to deliver superior performance and innovative features, all within a miniature surface mount package.
The introduction of new digital modulation schemes coupled with consumer demand for increased bandwidth and data capacity, have accelerated the need for microwave radio backhaul systems. These radios require integrated synthesizers that deliver high accuracy and can support signals with exceptional signal-to-noise-ratio (SNR). The phase noise and distortion of the synthesizer can limit the maximum achievable SNR of a modulated signal, while increases in the data throughput of the radio place an even greater demand on the synthesizer phase noise. In addition, synthesizer spurious products and far out noise, must be kept to a minimum so as not to impair transceivers operating in adjacent bands.
