Hi dear people,
Right now I've checked different sites to find the right component for my transmitter/receiver system, like mouser and TI. They have tons of different RF IC and I cannot decide which one to choose. The optimal is the most basic design.
As this is my first time designing a RF circuit I need you to push me into the right directions, and that would really be appreciated. And I can't push this project any further just because I am afraid of failure.
Specifications:
I have seen circuits that has all components needed integrated into one IC:
Which is easier, a circuit that has all these integreated or all separate?
Would you recommend me another architecture as a newbie?
I hope I'm not asking for to much here, also that I've provided enough information for you to help me.
PS. I have read a course in radioelectronics, so I know the theory but Im a bit unsure about the practical part.
Cheers!

Specifications:
- Frequency range: 2.4GHz or ~5GHz band
- Architecture: Direct conversion (Quadrature modulator)
- Transmit power: ~100mW
I have seen circuits that has all components needed integrated into one IC:
- VCO
- PLL
- Quadr. modulator/mixer
- LNA, PA
- Filters

bro i'v been working on PA and it completely fulfills your specifications. it can go upto GHZ range and could esily have Pout of 30dBm (greater than what u want) easily, besides u can get a hand on different research papers also. my advice u shud go for PA. :)
Hey mate,
A transmitter would be ideal as the last stage in the transmitter. If that is what you mean. However, I am still in need of help of which components to choose to build a basic transmitter/receiver system.
Thanks
