33 / 68 page  DocID025925 Rev 2 33/68 AN4444 ST7590 reference design description 68 Reception optional amplifier An additional all-pass amplifier has been included as an option to extend the dynamic range of the communication. The gain of the external amplifier only (to be combined with the reception passive filter response) can be calculated as: Equation 7 This extra gain could lead to ST7590 Rx input stage saturation if the input signal is very strong. In that case, an automatic algorithm has been implemented to attenuate the input signal. This attenuation can be calculated as: Equation 8 Figure 22 and Figure 23 report the measured frequency response in amplification and attenuation cases, compared with the passive filter response. Figure 24 and Figure 25 show the result of Montecarlo simulation for the same cases. Figure 22. Measured frequency response of the reception external amplifier + passive filter (higher curve) vs. reception passive filter only (lower curve) dB 10.9 = 3.5 39 36 38 R R R G RX dB 0 99 . 0 // // // 40 36 39 38 40 36 39 40 36 R R R R R R R R R G RX |
