Discussion of various RF filter technologies, and the progression of recent innovations delivering the newest levels in RF filter performance applicable for Satcom and Radar. Describing solutions spanning 240MHz MUOS UHF through L-band SatCom (Iridum and InMarSat) to Ku-Band and Ka-Band Satcom (Uplink and Downlink) with a fraction of the Size, Weight, and Cost for […]
Read moreA new microwave measurement receiver calibrates signal generators and attenuators providing tuned RF level measurements, level measurements, analog modulation and spectrum analysis. To measure the phase noise of the generators a powerful hardware for high end phase noise test is incorporated, with cross correlation for increased sensitivity. Due to real-time demodulation amplitude and phase noise […]
Read moreWhen testing up and down-conversion systems in agile radars, it is often necessary to isolate the performance of the internal local oscillators (LOs). Using a high quality and fast switching signal generator as a substitute LO allows engineers to isolate the true performance of their convertor chain. It enables them to evaluate signal chains without […]
Read moreAddressing the challenges of mmWave radar development with yield, material performances and innovations in architectures in support of mixed material PCB stack ups and thermal management of next generation Radar IC’s.
Read moreToday’s RF and radio system architecture can be divided into three separate blocks: the up/down converter, the baseband processor, and the RF front end. Presently, there are three highly integrated radio solutions to consider depending on your operating frequency and bandwidth requirements: integrated transceiver ICs, which operate from 30-6000 MHz and offer bandwidth of 12 […]
Read moreThe normal variation of several processes within circuit fabrication, can have multiple influences on RF performance. For some situations, the RF influence due to a process having normal variation can be significant at lower frequencies and less influential at higher frequencies. However, it is more common for the higher frequency applications to be more influenced […]
Read moreRF/microwave IP, developed in a specialized design environment, must be transferred to a PCB layout editor where manufacturing constraints, design rule checking (DRC), layout vs. schematic (LVS) and corporate-approved components can be applied and integrated with the power and digital electronics. The transfer of RF design data (schematic and layout) is tyopically re-entered manually by […]
Read moreIn designing via breakouts for BGAs, connectors and freestanding via transitions, engineers may box themselves into a corner where layout is exceedingly difficult. Designers may also fall into the “mole hole” of endless optimization simulations that seem more like a game of “Whack-a-Mole” than a design methodology. This presentation will provide a simplified process that […]
Read moreWith the 5G challenge of Massive MIMO and ever-increasing levels of density, this paper addresses the design and performance challenges of tightly packed RF components in 5G RRU’s and focuses on passive component placement and performance optimization in small form factors.
Read more5G and Wi-Fi 6 communication systems offer the promise of fast data rates. Core to achieving this performance is the fidelity of the up and down-conversion signal chains. When symbol errors exist, one potential source is poor phase noise of system local oscillators (LOs). To troubleshoot, engineers can utilize low phase noise synthesizers as an […]
