Overview
1. Brief Introduction
The traversing machine countermeasures digital modulation power amplifier module is a traversing machine countermeasure module
that includes a countermeasure signal source and a power amplifier. It can be used directly after connecting to the antenna.
The module uses an FPGA logic chip as the main control, combined with the excellent frequency stability of the frequency-locked VCO to create an anti-travel machine digital modulation signal plus power amplifier module.
The digital modulation signal is generated internally by the FPGA, modulated on the carrier with the VCO as the oscillation
frequency, and is emitted through the countermeasures process of the antenna.
The module uses a 50Ω SMA radio frequency interface output, which can be easily connected to the SMA interface power amplifier module.
2.Performance Characteristics
1)Supported frequency: 300-1200MHz, 2.4GHz, etc.
2)Output power: 50W
3)Small size, convenient for user integration
4)Industrial-grade application design, using industrial-grade chips, suitable for industrial-grade applications
5)Can effectively and accurately counter FPV drones
3.Basic functions
Set the digital modulation signal parameters of the counter source according to the remote control frequency band of the FPV , and modulate to the customized frequency band. The modulated counter signal is filtered through the RF front stage and output to the antenna through power amplification, forming the wireless signal of the remote control signal of the counter crossing machine.
4.Application instructions
The module power source is 24~28V, the module design is small for machine integration; the RF output SMA port of digital modulation amplifier counter module is impedance 50 Ω interface, the output transmission antenna, and the interface impedance must be consistent.The integrated working temperature should not exceed the working temperature of the module, and ensure good heat dissipation.
5.Use frequency range
The customized frequency band corresponds to the remote control signal of the FPV DRONE , and the countermeasures over the frequency range has no effect.
6.Interference distance and output power configuration
The interference distance is related to the output power of the power amplifier and the transmitting antenna. The greater the antenna gain, the greater the output power, and the farther the counter distance. At the same time, the best effect is in the unshielding environment, that is, no shielding between the counter signal and the FPV drone.
