• Pout >200W at any frequency  in working frequency band
• LDMOS Device  ensure high efficiency and ultra broadband.
• Continuous wave output  suitable for  CW ,FM or AM modulation
• ALC control function of output power  or working current
• Over-high VSWR to avoid or reduce the damage from any mismatch
• Protection  over  short or open of output port
• Pout and Gain of Temperature  compensation
• Over-high temperature protection, Shutdown more than 75℃, auto-restart less than 50℃

Competitive Advantage:

• Output Power is stable 53dBm±0.5dB over full temperature range (-25℃ to 80℃) at same Frequency
• Output Power is stable 53dBm±0.5dB over full working Frequency band at same temperature
• LDMOS Device ensure low Spurious emission and low Harmonics emission,
• Continuous wave output is suitable for CW ,FM or AM modulation
• 31dB attenuation is easy to control gain and Pout
• 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

Drones are one of the main forms of conflict in the current market. Countering and jamming drones is the main contradiction. Interference and jamming of drones start from the following aspects:

At present, remote control transmitters have generally adopted frequency hopping and spread spectrum technology, and the frequency hopping parameters can also be adaptive, with a certain anti-interference ability. When calculating the required interference size, the parameters of frequency hopping and spread spectrum must be known to obtain accurate results. However, we can still know the approximate range of the required interference. The remote control transmitter still uses the above parameters. Assuming that the defender is 100 meters away from the drone and the antenna gain is 3dB, if relevant interference is used, the required interference power is close to the remote control transmission power, that is, more than 0.1W. If there are frequency hopping measures in the remote control signal, and the interferer does not know any parameters of these measures except the frequency band range, and can only use noise for full-band violent coverage, then the required power will be increased. As a rule of thumb, it is usually necessary to increase by 30dB, specifically 200W.
