milstar: he Continuing Role of TWTsAlthough developments in GaN and LDMOS technologies have boosted the power output of solid state amplifiers, TWTs are still the benchmark in performance and efficiency for many applications. For example, for multi-octave high power generation, TMS TWTs are smaller, lighter, and more efficient than equivalent SSPA assemblies https://www.teledynedefenseelectronics.com/mec/Products/Documents/TWT%20Product%20Selection%20Guide.pdf EW and RadarShadow Gridded Helix TWTs for Broadband EW and Radar Applications from L through Ku Bands at Peak Power Levels to 12 kW and Average Power Levels to >700 W.

milstar: К 2016 г. на НПП «Исток» было освоено серийное производство СВЧ-модулей на арсениде галлия, технологии изготовления передних и боковых АФАР переданы на Государственный Рязанский приборный завод. Как показывает мировая практика, дальнейшее развитие АФАР связано с освоением технологии создания приемо-передающих модулей (ППМ) на основе нитрида галлия. К сожалению, как в 2019 г. в интервью журналу «Национальная оборона» отмечал Юрий Белый, на государственном уровне программы по освоению нитрид-галлиевой технологии для ППМ АФАР, которая бы увязывала всю линию, начиная от сырья и дальше по всем технологическим цепочкам, до сих пор нет. В результате по этому направлению Россию сейчас опережают не только США, но и КНР. https://oborona.ru/product/kedrov-ilya/radiolokacionnyj-kompleks-belka-dlya-istrebitelya-su-57-tekhnologicheskij-shedevr-sozdannyj-niip-im-v-v-tihomirova-42234.shtml

milstar: MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model BMCAP99109-1500 gallium nitride (GaN) solid state power amplifier module for X-band radar applications. The X-band power amplifier operates at frequencies of 9 to 10 GHz, 9.0-10 GHz, and offers typical peak output power of 1500 Watts. The AB linear design features pulse width and duty factor protection as well as thermal and load voltage standing wave ratio (VSWR) fault monitoring. The gallium nitride amplifier has an optional digital interface for control and status monitoring, and offers fast blanking and low phase noise. The amplifier offers power gain of 62 decibels nominal; power gain variation of ±2 decibels; pulse width of 0.25 to 100 microseconds; duty cycle of less than 6 percent; pulse droop of less than 0.015 decibels per microsecond; pulse rise & fall time of less than 50 nanoseconds; input VSWR of less than 2:1 output load VSWR of less than 2:1. Related: Gallium nitride RF and microwave amplifier for rugged X-band radar applications introduced by Comtech PST The amplifier has an RF input sample of -15 decibels relative to carrier (dBc); RF Pulse of on-off isolation of more than 110 dBc; DC voltage input of 28 volts DC; DC supply current of 12.5 amps RF to DC; and efficiency of 25 percent. The RF and microwave amplifier operates in temperatures from -40 to 65 degrees Celsius at the baseplate; operates in humidity of 0 to 95 percent non-condensing; offers resistance to the effects of operating shock and vibration per MIL-STD-810F; and operates at altitudes to 30,000 feet. The amplifier measures 9.6 by 6.8 by 2 inches, and weighs 5.5 pounds.
