Need help picking the right IC

[Vadim]

I am looking for a smallest size transceiver with an antenna done as part of the PCB layout (no external antenna needed). The simplest RF PCB layout is preferred, single frequency channel is enough,3.3V or 5V operation, just sending a carrier frequency is enough (no need for microcontroller or a communication protocol). Distance is 1-2 meters.

Hi

If you are looking for small size with antenna included you probably want to have a look at the list of 3rd party modules.
For instance the Taiyo Yuden modules for the nRF52832 are pretty small.

The nRF52832 will need some firmware to run.

We stopped doing radio only device a while ago, and the latest device we released without an MCU was the nRF24L01+.

Unfortunately we don't have the same selection of modules available for this part.

Both the nRF52 series devices, and the nRF24L01+, can be put into a simple TX carrier mode where no data is being sent.

Best regards
