V_CC= 4.4V to 5.25V

Figure 4-1 shows a typical 433.92MHz V_CC= 4.4V to 5.25V RKE car application. The external components are 11

capacitors, 1 resistor, 4 inductors, a SAW filter and a crystal. C₁, C₃and C₄are 68nF voltage supply blocking capacitors. C₂

is a 2.2µF supply blocking capacitor for the internal voltage regulator. C₅is a 10nF supply blocking capacitor. C₆is a 15nF

fixed capacitor used for the internal quasi-peak detector and for the high-pass frequency of the data filter. C₇to C₁₁are RF

matching capacitors in the range of 1pF to 33pF. L₂to L₄are matching inductors of about 5.6nH to 56nH. A load capacitor for

the crystal of 9pF is integrated. R₁is typically 22kand sets the output power at RF_OUTto about 10dBmSince a quarter

wave or PCB antenna, which has high efficiency and wideband operation, is typically used here, it is recommended to use a

SAW filter to achieve high sensitivity in case of powerful out-of-band blockers. L₁, C₁₀and C₉together form a low-pass filter,

which is needed to filter out the harmonics in the transmitted signal to meet regulations.
