Analog Devices, a world-class supplier of complete MMIC based solutions for communication and military markets, has developed the HMC832LP6GE, a 3.3 V wideband fractional-N PLL with integrated VCO that generates continuous fractional frequencies between 25 MHz and 3 GHz. The HMC832LP6GE offers low power consumption of 560 mW while featuring industry-leading phase noise and spurious performance. It also includes innovative, programmable performance technology that allows designers to further reduce current consumption if demands on the noise floor can be relaxed.

With industry-leading phase noise (-110 dBc/Hz at 3 GHz) and spurious performance, across all frequencies, the HMC832LP6GE helps designers minimize blocker effects, improve receiver sensitivity, and increase transmitter spectral purity. The best-in-class EVM performance satisfies the most demanding applications in cellular and microwave backhaul markets. When used as a LO in the IF stage of point-to-point microwave applications, the HMC832LP6GE limits phase noise contribution to the system SNR budget, and enables radio designs which utilize the highest constellations, such as 2048 and 4096 QAM. In OFDM systems, such as LTE and WiMAX, the HMC832LP6GE ensures that inter carrier interference (ICI) caused by the LO phase noise does not limit system SNR, thereby providing more design options and reducing the need for DSP resources associated with common phase error (CPE) correction and ICI mitigation.
