Electrical Specifications
4.1.10.8 Sub-GHz RF Receiver Characteristics in the 433 MHz Band
Unless otherwise indicated, typical conditions are: T_OP = 25 °C,VREGVDD = AVDD = IOVDD = 3.3 V, DVDD = RFVDD = PAVDD.
RFVDD and PAVDD path is filtered using ferrites. Crystal frequency=38.4MHz. RF center frequency 433 MHz. Test circuit according to
Figure 5.2 EFR32BG1 Typical Application Circuit: Configuration with DC-DC converter (PAVDD from VDCDC) on page 98 and Fig-
ure 5.5 Typical Sub-GHz RF impedance-matching network circuits on page 101. Unless otherwise indicated, all interferer tests have
been performed with an unmodulated (CW) interferer with the desired signal 3 dB above sensitivity limit.
