NRF403 Datasheet, PDF (8/15 Pages) List of Unclassifed Manufacturers – 315/433 MHz Single Chip RF Transceiver

PRODUCT SPECIFICATION
nRF403 Single Chip RF Transceiver
RF output power
The external bias resistor R3 connected between the RF_PWR pin and VSS sets the
output power. The RF output power may be set to levels up to +10dBm. In Figure 8
the output power is plotted for power levels down to, but not limited to, -8.5dBm for a
differential load of 400Ω. DC power supply current versus external bias resistor value
is shown in Figure 9.
