stealth Microwave amplifier SM1415-50LD

Post by Hellerx » Thu Dec 14, 2023 9:29 pm

Hi
I desperately need help here.
I have stealth Microwave SM1415-50LD with 1400mhz, 100w amplifier. What software and device controller can i use to read the data from the 10 pin port, as in the device data sheet, like the temperature, reflected power and forwarded power.

Hi Hellerx


These are voltage levels.

Pin 6 for example will measure 5V when the device is at 80 degrees C

Pin 3 will measure 5V at full power.

Pin 7 will measure 5V when there is no load attached.
Presumably 0v when into 50 Ohms.

You could use an arduino to read these voltages and display them.

On the two sheets it does not show if these levels are linear, ie is fwd power 2.5V at half power etc so you will have to experiment with this.

Thanks G1BVI for the reply
I did that already, but i needed more accurate reading's , i just thought here i will find
Someone who's dealt with this kind of equipment before.

Don't conflate reading accuracy with measurement accuracy. The Arduino is probably more than sufficient, as long as the ADC reference is accurate. IF not, a simple I2C 16 bit ADC like the ADS1115 should be.
