Hi,

?

does anyone have any information about this Watkins Johnson 6203-044 or HP part number 0955-0215 amplifier?

?

I am interested in its gain and frequency response in order to make a comparison with the one I have.

?

Thanks for the answer, do you have the information for the flatness? My amp must be defective, it has 26dB of gain at 10 MHz and 30 dB at 2 GHz.

38dB gain
10 MHz - 2 GHz
VSWR 2.0 max

Hi Vladan,

?

there was a problem with the amplifier, it had a variable gain, especially in low frequency, the cause: bad ground contacts by the PCB screws not tight enough. Now everything is stable, and the gain is 38dB in the middle of the band, the flatness about 1.2dB. Thanks for the information.

No, I don't have any information about its flatness, but the numbers you give are too far off. I don't know the P1dB specification either. Given the relatively high gain, make sure you didn't test with a signal that's too strong. Also, check the return loss. That may confirm if it's defective.

Thank you very much for this information
