200 Mhz may be massive for communications (especially digital encoded signals), not necessarily for radar when you sensor is receiving weak reflected signals that very likely can have a frequency shift on reflection. So radar receivers need to receive on a wider frequency band than a receiver for communications. Depending on the strength of 5G transmitters the higher order harmonics could be above the noise floor.
