Where F
pattern in RXCFG10 bits 3..0. Using a standard 12.8 MHz crystal, the equation for determining J is:
J must be an integer value, so F
not an integer for your deviation and bit rate, round the value of J down to the nearest integer and use this value
to set the bandwidth of the receiver Butterworth filters for the bit rate you are using. For operation at 133 kb/s and
above, use a value of 15 for J.
The recommended 3 dB bandwidth for the receiver R-C filters is:

6.2.2 Determining Transmitter Power Configuration Values
European ETSI EN 300 220-1 regulates unlicensed radio operation in the 433.05 to 434.97 MHz band. A
transmitter power level up to 10 dBm can be used in this band, subject to certain restrictions. See EN 300 220-1
for details.
FCC Part 15 and Canadian RSS-210 regulate unlicensed radio operation in several bands covered by the
TRC105. The allowed transmitter power level (field strength) depends on the operating frequency and application.
See these documents for details.
The use of the TRC105 is supported by various radio regulations in almost every geographic location in the world.
Please contact RFM’s local Field Application Engineer for additional information.
The relationship of the transmitter power level to the integer value of TXCFG1A bits 3..1 is given in Table 60.
There are eight available power settings (approximate):
