Note:

This parameter is characterized but not tested in manufacturing.
The following are the typical conditions for the measurement:
- Operating Conditions:
  - VDD = 3.3V and Temperature at 25°C
  - CPU is running on Flash with two Wait states in PL2
  - Low power cache is enabled and BOD33 (Brown-out detector on On-chip Switching mode regulator output (VSWOUT)/battery input voltage (VBAT) is disabled
  - Transceiver conditions as specified in the table
- Oscillators:
  - XOSC (crystal oscillator) is disabled
  - When MCU is in Active Performance Level 2 (PL2) mode, the DFLL48M is running at 48 MHz in Open-Loop mode
- Clocks:
  - In the PL2 mode, DFLL48M is running in the Open-Loop mode and is used as the main clock source
  - The clock masks and dividers are at Reset values: All AHB and APB clocks are enabled, CPUDIV = 1, BUPDIV = 1 and LPDIV = 1
  - I/Os are configured in the Digital Functionality Disabled mode. Except for PA04 and PA05, which are used to provide the UART input to the device
RF output is terminated with 50Ω when the module is transmitting a Continuous Wave (CW) tone
