No complaints about the designs, just curious, as Taiwan is making some supply chain people nervous... Steve https://forum.microwaves101.com/discussion/195/awr-demicrowave-office Wed, 05 Oct 2022 14:57:39 Z ArtyomJR 195@/discussions How to calculate RMS Phase and Amplitude Errors for Digital Attenuator in AWR DE. It's easy to calculate by hand, but hard in AWR I need the correct entry of the equations in the "Output Equations". Please help me. https://forum.microwaves101.com/discussion/173/new-4-phase-oscillator Mon, 19 Jul 2021 15:07:19 Z Richard 173@/discussions A pair of critically coupled tuned circuits, if you current drive one of them you get a voltage on the other which is 90deg phase shifted at centre frequency. The phase slope (group delay) is twice what you'd get with a single circuit. Two pairs, and two differential amplifiers, make an oscillator... https://forum.microwaves101.com/discussion/171/harmonic-tuning-at-30-ghz Mon, 12 Jul 2021 17:13:18 Z UnknownEditor 171@/discussions This is a comment not a question I have lost count of how many talks I have been to on millimeterwave amps and I asked about harmonic tuning. The answer is always condescending, like, Steve, you dumbass, there's no gain at 2F0 so no need... This paper seems to vindicate the idea. The highest... https://forum.microwaves101.com/discussion/158/self-biased-amplifier-large-signal Sun, 07 Feb 2021 18:58:22 Z UnknownEditor 158@/discussions Does anyone have any data (or ideas) on what happens to drain current when a self-biased LNA is driven to compression? It seems like the source resistor will counteract the normal tendency for current to rise... because the current would drive the gate closer to pinch-off. Could the current... https://forum.microwaves101.com/discussion/78/19-21-ghz-phase-shifters Sat, 20 Jun 2020 18:13:01 Z UnknownEditor 78@/discussions Does anyone know of any phase shifter MMICs that cover Ka-band SatCom frequency band? Roughly 19-21 GHz... Is there some reason or back-story why this band is under-served by MMIC suppliers? Thanks Steve https://forum.microwaves101.com/discussion/81/low-noise-amplifier-lna-using-ce3520k3 Fri, 02 Aug 2019 19:16:41 Z sMall 81@/discussions I am designing an LNA at 24 GHz using the discrete RF FET CE3520K3. I am implementing this design on 10 mil Rogers 4350B substrate. Just by looking at the S parameters (attached), I can see that the FET itself is inherently unstable at frequencies below 11GHz. So, I have been trying to make the LNA... https://forum.microwaves101.com/discussion/64/wideband-mmic-da-amplifier-biasing Tue, 28 May 2019 11:28:20 Z teleko7 64@/discussions Hi all First of all, thanks and congratulations to all the people in MW101. I think this is in the top 3 (#1) of the MW resources out there!! I've designed and fabricated my forst version of a 1 to 40GHz DA MMIC (GaN on Si), with 20dB gain and Pout >1W P1dB for the whole bandwidth (hopefuly). Input...
