RF Module
This RF module executes all RF functions of the module. RF circuitry is located on one
side (B-side) of the PCB.
EMC leakage is prevented by three metal shields. The first one includes the Bluetooth
module. The second block includes the PA, antenna switch, LNAs and dual RX SAW. The
last block include the Hagar RF IC, VCO, VCTCXO, baluns and balanced filters.
Maximum height inside on RF-shields is 3 mm. Heat generated by the circuitry will be
conducted out via the PWB ground planes.
Heat generated by the circuitry is conducted out via the PWB ground planes.
Normal and extreme voltages for RF block
There is no extreme voltage due of the internal power block and no battery use.
