* Recommended choke is Siemens Matsushita B78108-S1153-K or B78148-S1153-K (Qmin=60, max. DC resistance=0.6 Ω).
The power supply filtering is recommended for good EMI per-
formance. Use short tracks from the inductor L1/L2 to the mod-
ule VCC–RX/VCC–TX. We recommend a VEE plane under the
module for getting good EMI and sensitivity performance.
Reset is only possible if the power is turned off, and then on
again. VCCTX switched below VTH. Further application notes for
electrical interfacing are available upon request. Ask for App-
note 82.
Studs should be connected to this VEE plane. The transceiver
contains an automatic shutdown circuit.
Application board available on request.
