ATA5756/ATA5757
The 0.66 pF output capacitance absorbed into the load impedance a real impedance of 684
(ATA5756) at 315 MHz and 623
(ATA5757) at 433.92 MHz should be measured with a net-
work analyses at pin 5 (ANT1) with the ATA5756/ATA5757 soldered, an optimized antenna
connected and the power amplifier switched off.
Less output power is achieved by lowering the real parallel part where the parallel imaginary part
should be kept constant. Lowering the real part of the load impedance also reduces the supply
voltage dependency of the output power.
Output power measurement can be done with the circuit as shown in Figure 4-6. Please note
that the component values must be changed to compensate the individual board parasitics until
the ATA5756/ATA5757 has the right load impedance. Also, the damping of the cable used to
measure the output power must be calibrated.
