[SOLVED] Bias tee and resistor decade box - Suggestion

[palmeiras]

Hello Guys,

Please, I need to buy a Bias tee to bias a source follower (Connector 1: RF + DC, Connector 2: DC (input) and Connector 3: RF (output - connect it in the spectrum analyzer).
The RF signal is 2.5 GHz.

Do you have a suggestion of a good brand and where to buy it?

I also need a variable load (like resistor decade box with BNC connection), where the resistance varies from 50 to 50 kohm. Do you have a suggestion?

Thank you so much,

You didn't say what power levels you needed for the resistances.

have not used a decade boxy in ... decades. They have so much wire length inside of them that they are fairly useless in modern electronics, even a simple op amp will oscillate with one in the circuit.
