Hi Maker Community,
I need to power up and power down a RF LNA (Low Noise Amplifier), however I need to do this remotely. So far I know I’ll probably need an Arduino Uno, 12V Relay Module and a ESP8266 or some type of Wi-Fi module to send commands and determine the current switch connection of the relay.
My goal is to remotely control the switch through maybe an Arduino with Wifi, so that when I want it to power up, the LNA will be connected to the power supply, and it will power-down when the LNA is connected to the GND (Ground).
Power Specifications of the LNA
Supply Voltage: 12 to 15 V
Current Consumption: 400mA
Power-up Time = 300 microseconds
Here’s is a rough layout of the LNA, Power Supply and SPDT (single pull double throw) Switch
Any help or advice would be greatly appreciated
