I want to build a bidirectional wireless communication system with an operating frequency of SUB-100MHz. The system requirements are relatively small. NOW, Can I use ADF7021 to complete my request?

I see that its minimum operating frequency is 80MHZ, right? Can it send and receive normally at this frequency?

please answer
