When testing and calibrating electronic equipment, a dummy load is used that consumes electrical energy in a way similar to an actual or real expected load of the device under test. It is manufactured with internal resistors, capacitors, or inductors to change electrical energy into heat and other forms of energy. A dummy load is […]

There are various horn antennas including sectoral (15dB gain), conical (10-20dB gain), pyramidal (15-25dB gain), and exponential horns, each suitable for different frequency ranges and applications. Sectoral Horn antenna (Sectoral Horn) The gain of the fan-shaped horn antenna is usually between 12dB and 20dB, and the signal gain can be increased to 18dB by using

Antenna boosters focus signal direction, increasing strength by up to 100x (20dB), while amplifiers boost power directly, enhancing signal strength by up to 1000x (70dB). Antenna Booster Antenna gainers enhance signal strength by optimizing the reception performance of the antenna, which uses high-gain antennas or reflectors to focus the signal in a specific direction, thereby

The waveguide horn antenna is a widely used important antenna type in microwave and millimeter-wave communications. It combines the advantages of waveguides and horn antennas, transmitting microwave signals through the waveguide and utilizing the horn mouth to achieve signal radiation and reception. The waveguide horn antenna has excellent directionality, high gain, and wide bandwidth characteristics

The impedance of a rectangular waveguide wave varies by mode. For the common TE10 mode at 10 GHz, if the waveguide’s wide side is 2.286 cm, the characteristic impedance is approximately 377 ohms, calculated using the formula 𝑍=𝜂1−(𝜆2𝑎)2Z= 1−( 2aλ​ ) 2 ​ η​ where 𝜂η is about 377 ohms. TE mode In the most

Place the antenna booster as close to the antenna as possible to minimize signal loss, ideally within one meter, as signal attenuation occurs at about 3dB per meter of coaxial cable. Near the antenna For the antenna amplifier to work best, it should be placed as close to the antenna as possible. The signal in

Horn antennas have limitations including large size, manufacturing costs ranging from $2000 to $5000, and a signal attenuation rate of approximately 6dB/km at high frequencies. Basic Principles of Horn Antenna Horn antennas are a common type of high-frequency antenna, whose basic principle involves directing electromagnetic waves into a horn-shaped structure to enhance signal radiation efficiency.

The TIA 568 standards include Cat 3, Cat 5e, Cat 6, Cat 6a, Cat 7, Cat 8, Multimode Fiber (MMF), and Singlemode Fiber (SMF), supporting various data transmission speeds and distances. Category 3 (Cat 3) Category 3, also known as Cat 3, is a cable that supports data transmission up to 16 MHz, primarily used

Waveguide to coax adapters are used to convert waveguide signals to coaxial cable signals, commonly used in the 0.5 GHz to 40 GHz frequency range, ensuring low insertion loss (approximately 0.2 dB), suitable for radar and communication systems. Main Parameters and Significance of Adapters The main parameters of waveguide to coax adapters include frequency range,

The structural standards for antenna supporting structures require materials to meet ASTM international standards, involve rigorous load testing up to 150% of the design load, and include detailed non-destructive weld inspections. Types and Functions of Antenna Support Structures Lattice towers are used for broadcast television towers and military radar stations, capable of supporting 10-ton antennas
