Ham Radio Es'Hail 2 QO-100 13cm 2400MHz S-Band 20W Power Amplifier DIY

Description

I am selling some used S band power amplifiers. They are removed from fully working devices, can be used in the QO100 ground station application.。
The amplifier has a good internal condition, PCB, but its housing case has some scratches which is not affecting the functionality.
Each amplifier will be fully tested before shipping.
The output connector of the amplifier is a SMA connector, and the input is a MMBX connector. A MMCX connector  goes to output direct coupler.
A Pluto SDR can drive this amplifier working at the desired band with no modifications needed
Added Note: This AP comes with a baseplate with uniform heat at the bottom and an aluminum shielding cavity processed by CNC. The appearance has scratches and the bottom coating is partially peeled off. However, the PCB is guaranteed to be flawless, and 100% will be delivered after energized gain measurement and power test.
(Priority is given to the amplifier with less defects in appearance when shipping)
Warning: Do not invert the main power supply. The 5V port requires 500mA current, and do not exceed the 6V voltage.
Otherwise it will be damaged
