Two-arm spiral antennas usually have wideband characteristics (these antennas usually have constant beam width and circular polarization over a broad range of frequencies), 1,2 and thus are suitable for communicating (transmitting and receiving) over bands of frequencies (multiple channels). At lower frequencies, for a given size, these antennas tend...

Frequency synthesis is the cornerstone of all RF and microwave systems. Often dictated by specifications that push technological, spatial and economic envelopes, the design and implementation of frequency sources can often run into hurdles that force performance, schedule, or cost compromises. Hittite Microwave has one of the most comprehensive...

Base station (BTS) RF front-end design has in the past put more emphasis on performance compared to cost and size. However, to meet the evolving needs of the wireless infrastructure industry, BTS designers today are facing more challenges. Achieving the desired RF performance is only part of the equation...
