RF rotary joints enable signal transfer between stationary and rotating parts, typically handling frequencies from 1 GHz to 40 GHz with insertion loss under 0.5 dB. They ensure efficient communication in systems like radar and satellite, often supporting power up to 5 kW at lower frequencies. Transmission Path At the Ku-band, 12-18 GHz; an RF […]

To choose the right coaxial attenuator, match the frequency range (e.g., DC-18 GHz for $50), attenuation value (e.g., 10 dB for $40), power handling (e.g., 100 watts for $150), and connector type (e.g., SMA or N-type) to your specific system needs. Frequency Range When selecting a coaxial attenuator, be sure the frequency range fits your

Parabolic dish antennas are ideal for long-distance communication, providing a gain of up to 47 dBi. For example, a 2.4-meter dish operates efficiently at 12 GHz, enabling satellite communication over 35,786 kilometers with power outputs of 1 to 10 kilowatts. Parabolic (Dish) Antennas Parabolic or Dish Antennas in Satellite Communications The parabolic dish antennas play

Flaring in horn antennas reduces phase errors, enhances gain, and improves impedance matching. For example, a flared horn at 10 GHz can boost gain by 6 dB, improving signal strength by 4 times. Proper flaring reduces phase errors below 5 degrees, ensuring accurate signal transmission. Impedance Matching In horn antennas, flaring is very important because
