first time designing RF, so pardon my ignorance. I want to design a ASK/OOK transmitter board operating on both 315Mhz and 433MHz ISM band frequencies. I have a MCU onboard that generates the data to be sent. I am hoping to use "data-in RF-out" transmitter IC like MICRF112 along with passive components and crystal.
Is there a way to use a single transmitter IC and have the RF-out switched between the 315MHz and 433Mhz RF arms. I think it may not be possible as the crystal that goes along with each frequency is different.
What would be the recommendation to minimize the BOM here - as most of the non-RF components are identical between the two transmitters? Thanks!
