Figure 3-1 shows a typical 433.92 MHz RKE key fob application. The external components are

10 capacitors, 1 resistor, 2 inductors and a crystal. C₁to C₃are 68 nF voltage supply blocking

capacitors. C₅is a 10 nF supply blocking capacitor. C₆is a 15 nF 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 1 pF to 33 pF. L₁is a matching inductor of about 5.6 nH to

56 nH. L₂is a feed inductor of about 120 nH. A load capacitor of 9 pF for the crystal is inte-

grated. R₁is typically 22 kΩ and sets the output power to about 5.5 dBm. The loop antenna’s

quality factor is somewhat reduced by this application due to the quality factor of L₂and the

RX/TX switch. On the other hand, this lower quality factor is necessary to have a robust design

with a bandwidth that is wide enough for production tolerances. Due to the single-ended and

ground-referenced design, the loop antenna can be a free-form wire around the application as it

is usually employed in RKE unidirectional systems. The ATA5823/ATA5824 provides sufficient

isolation and robust pulling behavior of internal circuits from the supply voltage as well as an

integrated VCO inductor to allow this. Since the efficiency of a loop antenna is proportional to the

square of the surrounded area, it is beneficial to have a large loop around the application board

with a lower quality factor to relax the tolerance specification of the RF matching components

and to get a high antenna efficiency in spite of their lower quality factor.
