• All of devices are new (including final RF power Amplifier),that assure high quality of modules
• Isolator is embedded in amplifier modules at output port, good VSWR and protect PA from damage.
• Coupling SMA port of output power are accurate -40dB ± 1dB,easy for monitoring
• With logarithmic RF Power detector, detector output of forward power and reversed power is linear-in-decibels.
• ALC control function with output power or working current
• Protection over High VSWR and shutdown

* Over-high VSWR to avoid or reduce the damage from any mismatch

• High Temperature Protection and re-start when temperature low down.

* Over-high temperature protection, Shutdown more than 75℃, auto-restart less than 50℃

• With temperature compensation and frequency compensation , output power and gain of RF PA is more steady.
• Monitoring and control I/O port of serial RS485 is optional

Remarks

• PA should be operating on an appropriate radiator, otherwise it will shut down by over high-temperature.
• Pout port cannot open or short, otherwise may burn and damage PA.
• Pout port should should be connect to a probably Load, Attenuator or antenna (50 ohms, more than 100W handling Power, lower than VSWR 2.0).
• The power supply range and polarity of power supply must be correct,  otherwise will damage the PA.
• Pout probably lower than the rated power when input Power less than 5dBm;  PA probably is damaged if Pin is higher than 12dBm

Description

• The selection of drone communication frequency depends on a variety of factors, including communication distance, data transmission rate, anti-interference ability, device compatibility, and local regulatory requirements. The following are some common drone communication frequencies and their characteristics:
• ‌433 MHz band. This is a low-power radio frequency band, commonly used for short-range communication and remote control applications. It is used for drone remote control and data transmission in some countries and regions, but its data transmission rate is low due to the limitation of spectrum resources. ‌
• ‌868 MHz band. This is a widely used radio frequency band in Europe for short-range communication of low-power devices. In some countries, drone image transmission systems can communicate in the 868 MHz band, but its bandwidth is low and suitable for transmitting lower-rate data.
• ‌1.4 GHz band. This is an optional radio wave band for drone image transmission systems. It provides relatively high bandwidth and long communication distance, and may also have good spectrum availability in some areas.
• 2.1 GHz band. Commonly used for mobile communication systems such as 3G and 4G networks. In some areas, this band can also be used for drone image transmission systems. It offers higher bandwidth and better data transmission capabilities, but may require special licensing or spectrum sharing in some areas.
• 840.5-845 MHz. Mainly used for the uplink remote control link of unmanned aircraft systems, that is, the drone receives signals from the remote control to execute flight operation instructions. ‌
• 1430-1444 MHz. Used for the downlink telemetry and information transmission link of unmanned aircraft systems, including data transmitted back from the drone. Among them, the 1430-1438 MHz band is designated for police unmanned aircraft and helicopter video transmission, while other unmanned aircraft use the 1438-1444 MHz band. ‌
• 2408-2440 MHz. This band is also planned for unmanned aircraft systems. The 2.4 GHz band has a longer wavelength, can better bypass obstacles, and provides a longer transmission distance, which is suitable for non-image transmission drones such as model aircraft. ‌
• 5.8 GHz band. This is a common radio wave band used for wireless video transmission and image transmission systems. It provides higher bandwidth and transmission rate, but is usually used in short-range communications. ‌
• Local regulations and licensing requirements must be considered when selecting and using drone communication frequencies to ensure compliance and avoid interference with other legitimate communication systems.
