Mungkin banyak dari kita yang yang belum tahu apa itu Gallium Nitride. Gallium nitride adalah material semikonduktor bandgap langsung biner III / V yang cocok untuk aplikasi transistor daya tinggi yang mampu beroperasi pada rentang suhu yang  jauh lebih tinggi dari transistor silikon biasa.  Sejak era 1990-an, Gallium nitride telah digunakan secara khusus dalam dioda pemancar cahaya atau (LED). Gallium nitride mengeluarkan cahaya berwarna biru yang digunakan untuk membaca disk dalam Blu-ray. Selain itu, gallium nitride juga digunakan dalam perangkat daya semikonduktor, seperti komponen RF, laser, dan fotonik. Silicone wafer Pada tahun 2006, transistor GaN peningkatan-mode, lebih dikenal sebagai FET GaN, transistor ini mulai diproduksi dengan menumbuhkan lapisan tipis GaN pada lapisan AIN dari sebuah wafer silikon standar menggunakan deposisi uap kimia logam organik (MOCVD). Lapisan A.I.N ini bertindak sebagai penyangga antara media dan GaN.

FM radio is an FM broadcast radio receiver (frequency modulation) that has the advantage of being able to transmit broadcasts in stereo format. despite having the advantage of sending stereo broadcasts, FM waves have a relatively short range. many electronic hobbyists want to make their own radio fm, but many circuit schemes use ic fm, and this is considered less challenging. Simple FM receiver circuit diagram the fm radio circuit scheme consisting of several transistors is a circuit scheme that is sought, because it is easier to understand how it works. this time I will share the fm radio circuit scheme consisting of several transistors.  some parts of the scheme of the FM receiver radio circuit use transistors, such as the RF amplifier, tuning, and if amplifier parts. with the use of transistors in the FM radio circuit scheme, this series can be used for learning materials about how a FM radio receiver works.

At present the world of aviation has been very advanced, this is evidenced by the rapid intercontinental flights, and accompanied by increasingly cheaper costs. All of this can be realized with the use of super materials, in the constituent components of an aircraft. To reduce flight costs, one way that can be applied is by reducing the weight of aircraft. In this way the aircraft fuel consumption becomes more efficient, so the cost of flights will be cheaper. To reduce the weight of an aircraft, for now using lightweight and strong carbon fiber and aluminum alloy materials. This material is very strong and has a light weight, so it can be used to make aircraft parts. In addition to the development of the fuselage, the scientists also developed another important part of the engine. As we all know airplane can take off, and fly because it gets thrust from a jet engine. Jet engines are one of the strongest engines on earth besides Rocket engines. The jet engine is ab...

FM receiver or FM radio is the most popular radio receiver for now. Its advantages, among others, can be used to transmit broadcasts with stereo format. So the music show on FM radio has better sound quality than AM radio. Many of the analogue electronics hobbyists consider that to make an FM receiver quite difficult. Because, many of the FM radio circulating using ic receiver so this makes us think it will be difficult to make it simpler.  For this time I will share the FM receiver scheme from the electronic kit of the 90s, and the receiver scheme is quite easy to make because it uses only some electronic components only. Simple FM receiver circuit diagram Basically this receiver scheme is a rf circuit amplifier, oscillator, and audio amplifier made very simple. Hopefully this FM  receiver scheme can help you with your FM receiver project. Simple FM receiver circuit diagram Simple FM receiver circuit diagram

In this modern era all electronic devices have grown rapidly. Starting from home appliances, communication tools, vehicles, and much more. It used to communicate telephone lines using cables, to apply radio frequency waves for home phones to mobile phones. In addition to being applied to telephones, radio frequency waves also have long been applied to two way radios or walkie talkies. In the eighties, walkie-talkies were very popular to communicate at close range. And many walkie talkie kits are available on the market almost all over the world.  But for now walkie talkie kits are hard to find, but still available in some online stores.  For people who have a hobby of electronics, making your own walkie talkie is a fun thing. There is a certain satisfaction when we can make wireless devices with our own hands. For that moment I will share a series of walkie talkie toys that many circulating in the market. This walkie talkie circuit is quite easy to make, becaus...

Have you ever wondered, what is the furthest thing that man has made? Perhaps many think, that man-made furry thing is mars lander. Or maybe a satellite to research jupiter. However, in fact the man-made furry thing is a pilotless aircraft with ancient technology. The plane was a voyager 1 launched on September 5, 1977. The main mission of the voyager 1 was to investigate the planet of jupiter and saturnus, but improved again to examine the heliopause and interstellar space. On March 5, 1979, voyager 1 reached the planet of jupiter, and on November 12, 1980 the voyager 1 reached the planet of saturnus. The voyager 1 power is 420 watts, sourced from thermoelectric generator radioisotopes. To communicate with the earth, voyager 1 uses a power transmitter of only about 22 watts, and it takes about 36 hours to communicate with the station on earth. In 2015 the voyager 1 distance from the earth is about 19.7 billion kilometers, and to date the voyager 1 continues to go and awa...
