11 / 16 page MC33492 PLL Tuned UHF Transmitter for Data Transfer Applications 11 OUTPUT POWER MEASUREMENT The RF output levels given in the electrical characteristics section are measured whith a 50 Ω load directly connected to the pin RFOUT as shown below in figure 7. This wideband coupling method gives results independant of the application. Figure 7: Output power measurement configurations The configuration shown in figure 8-a provides a better efficiency in terms of output power and harmonics rejection. Schematic on figure 8-b gives the equivalent circuit of the pin RFOUT and impeder as well as the matching network components for 434MHz frequency band. Note that the impeder is moved to the load side to decrease its influence (similar to DC bias through the antenna). Figure 8: Ouput characteristic and matching network for 434MHz frequency band Figure 9 gives the output power versus the Rext resistor value with 50 Ω load and with matching network.
