  • Page 19: Rf Front End

    Chapter 3 RF Front End The MC13192EVB is designed to show a high performance, small form factor solution interfacing to a single antenna. A built in, high performance, PCB antenna enables the design to be evaluated as-is, while an SMA connector allows for easy RF testing and evaluation of other antenna designs. Other reference designs demonstrate low cost solutions, integrated antenna designs, and the lowest Bill of Material (BOM) count possible.

  • Page 20: The Transmit (Tx) Chain

    RF Front End The Transmit (TX) Chain The TX output is a differential open drain output, which should be loaded with a 200 Ohm differential to provide 2 dBm output power (nominal). A 50:200 Ohm balun is used to load the output correctly. A DC path from VDDA is necessary to supply the output stage and is provided via the center tap on the balun.

C102 provides better balance and added static protection. The inputs will stand the usual capacitive 150 pF discharge test, but it is more sensitive than the other pins.

  • Page 26: Internal Power Supplies

    RF Front End This inverter type reference oscillator requires two external load capacitors to resonate the crystal. Because the oscillator runs with a very low current draw (11 µA), crystals with a load capacitance of 6-8 pF are recommended to ensure proper oscillation. The crystal should also have a low Co value. A built-in switched capacitor bank allows fine tuning of the reference frequency.

    RF Front End 3.8.2 Output Filter L103 and C112 can be left out in many applications, but spurious performance should be tested. If the antenna does not have a DC connection to ground, C104 can be left out. 3.8.3 Switch In the case of a dual antenna approach, C103, C104, and the switch can be left out.

    RF Front End RF Measurements The measurements presented here are typical values as measured on the MC13192EVB. These values do not represent guaranteed performance. 3.9.1 RX Sensitivity The input level is adjusted until 100 mV RMS appears on GPIO4. Actual sensitivity at 1% Packet Error Rate (PER) is reached at approximately 20 mV PP at GPIO4, so a correction factor of 23 dB is employed.
