While traditional RF and microwave applications are predominantly focused on wireless communication or navigation, recent advances in device technology have opened up an exciting range of non-communication, non-navigation applications of RF and microwave power. Dielectric heating is an important part of any RF and microwave heating process.
Phase noise has been a growing concern for high-performance transceiver designs. This white paper will discuss and analyze the various sources of additive phase noise in RF amplifiers as well as typical application requirements and measurement challenges. Phase noise specifications for a series of MMIC amplifiers are presented.
Mini-Circuits has established a new office in Nijmegen to expand its corporate service and support presence for European customers. The new office will also serve as a hub for the company’s business development efforts in the global RF energy market.
A new class of filter, which presents broadband matched impedance at it's ports, has recently been invented and made available. This new device, the reflectionless filter, has demonstrated a variety of benefits when used to replace conventional filters in a signal chain. This white paper briefly introduces the reflectionless filter and compares conventional filter and reflectionless filter behavior. Use cases are presented examining how reflectionless filters can improve system performance when used with mixers, ADCs, and receiver signal chains. Lastly, an experiment is described and test results presented to compare the conversion loss ripple in multiplier chains when reflectionless and reflective filters are used to filter spurious signals.
