Hello , I have an amplfier board of QPA2575 the DC feeding GND Is at metal_3_bot while the RF signal has ground at metal_2_mid.
The DC connector is HUGE as shown below,basicly i need to simultaniosly feed all 4 amplifiers.
From looking at the data sheet i have this schemtics shown in the last photo.
How do i build a feeding network for such a complex connector so if will feed all 4 amplifiers shown in the schematics below.
Thanks.
Hello, i have an amplifier QPA2575 which data sheet is attached.
As you can see below, i put the layout as i imagine it in the schematics.
for example if i what to simultaniosly power the drain_top(red arrow) DC input i dont know do to properly draw the trace from the main drain_top connector, to the sub (drain_top) at each amplifier.
Is there any intuition regarding how to simultaniosly power all four amplifiers?
Thanks.
