Dual Directional Coupler, 9KHz~1GHz, 300W, 40dB

Dual directional coupler is a precise passive microwave/RF device. This product provides high-performance solutions for fields such as broadcast communication, high-power RF testing, scientific research, and EMC testing with its excellent ultra wide operating frequency band of 9KHz to 1GHz, average input power processing capability of up to 300 watts, and excellent 40dB directionality. The following briefly introduces its characteristics and applications:

Characteristics:

1. High power and high reliability: Adopting a special heat dissipation design and low loss transmission line structure, it ensures low insertion loss and excellent temperature stability even when operating at 300W full power, ensuring continuous and stable operation of the system 24/7.
2. Ultra wideband and flat response: It has extremely low frequency sensitivity throughout the entire frequency band, with small fluctuations in coupling, ensuring consistency of measurement results throughout the entire spectrum.
3. Precise monitoring and system protection: High directionality enables it to capture small changes in reflected power in a timely manner, providing critical early warning signals for power amplifiers, effectively preventing equipment damage caused by antenna mismatch and other faults, and reducing downtime risks.

Applications:

1. Precise monitoring and system protection: High directionality enables it to capture small changes in reflected power in a timely manner, providing critical early warning signals for power amplifiers, effectively preventing equipment damage caused by antenna mismatch and other faults, and reducing downtime risks.
