Hello,I have bought a PCB of an amplifier. The amplifier is like a lego.The problem with this is how do I bias it. I have rf_in rf_out But I dont know how to bias such things. What component do we use to deliver the DC into this amplifier component?
Is there some examples? Thanks.

If you're looking at the evaluation board, then you bias it with jumper cables connected to standard headers, which connect to the corresponding header pins, which I've circled in the picture. You supply the gate voltage to the headers circled in blue, and the drain/control voltage to the pins circled in red. RF I/O are the jacks J1 and J2.


If you've instead bought the module that looks like this:

Then you solder a wire to the hole where it says "VDD" and apply your 10V drain voltage to that pin.

The last page of the datasheet even tells you what to do for biasing, even if you didn't have that VDD pin:

However, it looks to me like that module has the necessary external bias-Tee built into the PCB, so all you need to do is attach a wire to that point.

You could of course solder a wire to the respective power supply pad on the MWblock and be done but that would imo defeat the purpose of LEGO style MW prototyping boards. Actual LEGO bricks don't need glue either.

There are matching bias/control boards available that go underneath the main protoplate. Shielded spring pins soldered to the bias board go through the protoplate and provide a solderless electrical connection to the MWblock. A wire soldered to the bias board connects to one of the DC feed-through capacitors on the universal bias/control interface board screwed to the side of the protoplate.

 

Hello,There is a manual shown below which showing in detail things I must have to assemble the tranciever.
for example:
1. connecting the two grids(tables) requires wall peaces and special bolts to connect them to the grid as shown below below.
but as you can see below there are many options for bolts and wall peaces.
2. there is a spring pin shown in the photo below.
The biasing network photo shown below doesnt have any spring pin inside.
Where can I find it?
3.more serios issues is with the finding the proper peaces for connecting the components together
Like in the last photo below I need jumper component and I need anchors.
there are virations of screws and anchors and jumpers.
Is there some example design where I can look a see the exact structure of each and I see what exact components I need to buy to implement it.
Is there such a thing?
Thanks.
