I've been working on learning transistor 101s, for a 900MHz transmitter.
I'm to the point, I can work the basic algebra, and intuitively understand changing the passive components in the transistor circuit to boost an RF signal.
I came across a wide bandwidth RF amplifer from NXP, the BGA2817.
Here is the BGA2817 Datasheet.
At a cost of $0.08/USD at volume, what is the downsides to using BGA2817 as an amplifier, versus going through all the development and trial and error of building up some transistor stages and amplifying your signal for a transmitter?
The one thing that sticks out to me is the 20mA supply current. Not really a deal breaker for a transmitter, but clearly a deal breaker for a receiver.
Are people moving over to this type of IC for RF amplification?
Why does this thing draw 20mA in the first place, when you get down to how this IC is built. I have no idea.
It doesn't get any easier to implement one of these, all the voltage step-up, impedance matching, and whatnot is just baked into the IC.
