The RF frontend has two local oscillators that allows reception and transmission on 2 bands of 900MHz in both UHF and SHF frequency bands.
It has also a 60 GHz frontend that allows transmission/reception in the 60GHz band. Below is presented the supported spectrum by the RF frontend:
The main objective is to integrate the antenna arrays provided by IMT-A in the RF mmWaves board. The synoptic of the Tx and Rx Analog front-ends are depicted below. The first objective is to pilot 2 main beams focusing user’s direction for video transmission.
Several technical locks @60 GHz:
- Integration process
- RF branches calibration
- RF branches mismatches
- RF Interference
- RF losses …
