YIG-based synthesizers that offer superior noise performance and wider bandwidths than typical dielectric resonator oscilllators and VCOs for quadrature amplitude modulation (QAM) digital radios
The Application of Low Noise, X-band Synthesizers to QAM Digital Radios Mark R. Simpson and John M. Dixon VertiCom Inc. Santa Rosa, CA For high data rate, 16-to-64-quadrature amplitude modulation (QAM) designs, the vast majority of wireless point-to-point and point-to-multipoint radio manufacturers currently are using fixed-frequency, mechanically adjustable dielectric...
