ARF448A/B

When my Ham friend Biju visited me last week, he mentioned about a low cost RF power amp circuit using MOSFETs called ARF448A and ARF448B (ARF448A/B). Here is the circuit(PDF File). And the datasheet for the same is available here.


Soon afterwards I started searching for these power MOSFETs and could not find even a single source over here in India. So, I finally came to this person from china who supplies these in bulk. Now the problem is how to buy around 500 pieces of these and how to get it to India without paying exorbitant duties and stuff like that. I am interested in a group buy. So, If any of you readers are interested, we can work something out, Please comment me with the desired number that you are willing to buy and how can you pay me etc. I will soon update this post with the invoice this contact of mine provides.

Lets see if we can have a cheap solid state linear amp for the HF spectrum.

Say good luck, Suckers!!! ;)
