433 MHZ FSK power amplifier plate radio amplifier input 19 DBM output 3~ 5 w

Description

433 MHZ FSK power amplifier plate radio amplifier input 19 DBM output 3~ 5 w
1 product introduction
This amplifier can increase the FSK launch distance of communication system, using the need to use former level FSK transceiver board provides two IO logic to control the amplifier and switch. 19 DBM power input can get a 3 w rf power output. Greatly increase the transmission power of FSK system, so as to increase the coverage.
2 products indicators
Input 19 DBM
Output 3 w power supply 7 v
5 w output 9 v power supply
The emission current 0.75 A
Working frequency 433 MHZ
The receive current 0 ma don't consume electricity
Receiving loss of 0.7 dB
4 use method
According to the above connection methods properly connected, when emission level of the board before using the TR CPU control logic is 10, then power amplifier in the launching state, level before the launch of the signal after amplifier power amplifier to the antenna to launch into the air. When receiving, before using the CPU control logic for TR 01 level board, power amplifier in the receiving state at this moment, antenna receiving the signal after amplifier for receiving demodulation to rf chip!
5 using note
This amplifier input 19 DBM, at the time of 7 v power supply output power to 3 w, in 9 v power supply power output can reach 5 w, use of time attention if intermittent launch can not consider power amplifier tube heat dissipation problem, please note if you need long time continuous emission power amplifier tube heat dissipation.
