The Basics of Patch Antennas, Updated - Orban Microwave
orbanmicrowave.comfringing fields and cause the patch to radiate. Some popular analytic modeling techniques for patch antennas are based on this leaky-cavity concept and the fundamental mode of a rectangular patch is often denoted using cavity theory like the TM10 mode. This TM notation often leads to confusion and here is an attempt to explain that:

RF Power Amplifiers - QSL.net
www.qsl.net• In theory 6dB or more drive power is needed to achieve Class-B compared with Class-A. In practice this 6dB reduction in power gain is lower; for BJT amplifiers is lower than FETs, approximately 2dB. • The efficiency of the push-pull power amplifier is …
