Intermediate Frequency in transceiver?
There are lots of details to take into account when designing a heterodyne receiver, more than just the mathematics of the frequencies.

Generally when down converting a receiver (upconverting a transmitter), each frequency conversion is to (from) an IF in the order of 5% to 10% of the RF frequency. There are exceptions, but this is what tends to work best, most easily, cheapest etc.

If you convert to a larger fraction, then the mixing process is susceptible to low order intermodulation distortion, and the receiver specification suffers.

If you convert to a smaller fraction, then the pre-mixer filter becomes very difficult to design and build.
