               Radio waves were first mapped out and harnessed back in 1873. Since that time, radio frequencies and microwaves have been used in numerous applications from the telegraph and the first radio broadcasts making their way into people's homes to radar technology and musical instruments. They also paved the way for military drones, satellites, and the internet among other modern-day essentials. GaAs, or gallium arsenide and GaN, or gallium nitride are the 2 most important semiconductor material that are used for building high-power microwave switches and amplifiers, more specifically TR module-based radar assemblies in fighter jets. While GaN has emerged as the leading semiconductor material for high-power microwave switches and amplifiers, GaAs is still the preferred material of choice for low noise. What and Why Are These Used For It's important to understand what semiconductors are and why they're important for RF power amplifiers. Conductors are mate

At the 16th BRICS summit in Kazan, Russia unveiled a symbolic   BRICS banknote , stirring debate over ending the US dollar's dominance. Russian President Vladimir Putin emphasized that the dollar is being used as a 'weapon,' but BRICS isn't rejecting the currency entirely, instead preparing alternatives for restricted access. India took center stage at the summit, advocating for local currency settlements among BRICS nations. The unveiling of the BRICS currency bill, featuring the Taj Mahal, is a way the BRICS bloc is trying to challenge the US dollar's global financial power. The banknote, which features the flags of Brazil, Russia, India, China, and South Africa, symbolizes the collective ambitions of these nations to explore alternatives to the US dollar in cross-border transactions. This development highlights the growing effort within BRICS to establish a more independent economic system that is less reliant on Western financial structures. Putin’s Stance o

  Recently, India won a deal to build 4 non-nuclear icebreaker ships estimated to be worth over Rs 6,000 crores for Russia. Russia’s state-owned nuclear energy company ROSATOM will seek “favorable and capable yards” in India to construct the ships to support its Northern Sea Route (NSR) development plan in the face of sanctions imposed by the USA and other countries. This brings to notice the nuclear icebreakers operated by Russia, the only nation to do so in the world. So why are we talking about nuclear icebreakers? It is because of the nuclear reactors in them that have been used in the Arihant class SSBNs of the Indian Navy. Many may not be aware that Russia provided the nuclear reactors of its nuclear icebreakers to be developed into reactors for S1/half-boat, S2/Arihant, S3/Arighaat, S4/Aridhaman, and the supposed S4*. Kindly note USA, the Soviet Union/Russia, China, France, and Britain hold nuclear reactor technology very d
