Planar transmission lines are used to carry a variety of analog, RF, and digital signals on insulative, planar substrates from kilohertz to hundreds of gigahertz frequencies. Planar transmission lines are constructed of one or more layers of metal traces with one or more parallel metal traces. There are several common types of planar transmission lines: ..

Though transmit/receive modules (TRMs) have been used for some time in active electronically scanned array (AESA) radar technology, the benefits of phased array antenna and multi-input-multi-output (MIMO) for 5G applications have brought this technology to the mainstream. Given that phase array antennas for millimeter-wave 5G may employ up to, and possibly beyond, 64 antennas elements ..

Given the stringent timing requirements of 5G network and wireless applications, RF oscillator performance is of increasingly critical importance. Noise and phase noise are among the most significant of these requirements, as these parameters have the greatest impact on communication signal quality and receiver capability. Though noise and phase noise have always been RF oscillator ..
