Attenuators are widely used with devices that do not have built-in power control to attenuate the signal during overload or loopback. Attenuators are also installed in amplification systems if the built-in adjustment means are not enough for the correct functioning of the equipment.

Sign in to order →The KROKS 50 Ohm 30 dB Attenuator is an ideal choice for drone control systems. It prevents signal overload, protecting equipment from damage. The device is suitable for devices without built-in power regulation.
The model is effective in circuits with a signal loop or when working with amplifiers. Built-in adjustments are often insufficient - KROKS compensates for this deficiency. The attenuator is compatible with most industrial and amateur drones.
KROKS is compatible with popular drone models: DJI Matrice, Autel EVO, Yuneec Typhoon. 0–3 GHz support covers frequencies of GPS, GLONASS and FPV systems. This simplifies integration without rebuilding the hardware.
The KROKS 50 Ohm attenuator can withstand extreme temperatures from -40°C to +85°C. This makes it suitable for use in any climate. The device is not afraid of vibrations, which is critical for drones in flight.
Protection against moisture and dust complies with IP67 standard. Even in rain or a sandstorm, the equipment will remain functional. The design eliminates overheating - the heat sink is designed for long-term loads.
The 0-3 GHz frequency range provides versatility for a variety of applications. SWR 1.02 minimizes signal loss, increasing data transmission accuracy. 30 dB insertion loss allows flexible power adjustment.
Average power of 10 W and pulsed power of 30 W guarantee stability during peak loads. Aluminum alloy body provides durability and efficient cooling. The N-connector guarantees a reliable connection without interference.
The attenuator is compact and easy to install. Suitable for field conditions and laboratory testing. Compatible with drone antennas, transmitters and receivers.
KROKS 50 Ohm is durable and accurate. Protect your equipment and optimize your control systems. Buy from aegisky - the official supplier of professional drone components.
