0.9GHz 50W Amplifier

Main uses: Control & Vedio transmission of  UAV & Drone

Key specification:

Pout >50W at any frequency in 0.4GHz or 0.9GHz or 2.4GHz

Pout>50W from -25℃ to 80℃

Description(short)

• Pout>50W from -25℃ to 80℃
• Pout >50W 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℃

Feature

Competitive Advantage:

• Output Power is stable 47dBm±0.5dB over full temperature range (-25℃ to 80℃) at same Frequency
• Output Power is stable 47dBm±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.
