• ALC (Auto Level Control) ensure high P1dB and high IP3.
• Select ROGERS Rogers high-frequency printed circuit board (PCB) to ensure stability of Amplifier modules
• All screws are made of stainless steel, the amplifier modules are corrosion-resistant
• 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 cheap receiver despreading scheme is too simplified and does not fully utilize the 43dB spreading gain.

The simplest broadband signal is noise frequency modulation. Of course, stronger correlation interference can also be used to deceive, such as using GPS simulators to generate some false signals. But considering that the interference power is already not large, it seems unnecessary to incur this expense.

The behavior of a drone after losing GPS signals depends on the functionality and settings of the flight control system. For skilled operators, GPS is not necessary. In the era without GPS, pilots of aerial models could still complete their envisioned flight routes through visual inspection or image transmission. However, for inexperienced operators, the consequences of eliminating GPS signals are already quite serious, as the automatic return function of the drone has become ineffective and must rely entirely on manual operation. Based on the defense experience already mastered, this is basically equivalent to not being able to fly back. If you want to avoid the consequences of GPS interference, you can write about the following points:

Combined with the antenna with a gain of 5dB, it can already defeat most brands of drones' GPS within a range of 100 meters. This may be caused by the following reasons:

• The operator must undergo training in GPS free flight.
• Strictly assess the ground isolation of GPS antennas to increase it to, for example, 50dB; Choose a GPS receiver with high performance.
• Adopting a higher precision inertial platform to ensure sufficient return time in the event of GPS loss.
• Utilize images from onboard cameras for localization and return.
