7.6. Reference Design Performance
Nominal VDD = 3.3 V
Tests performed at room temperature: 25° C +/-3° C
Center frequency 869 MHz or 915 MHz
{R, P, S} triplets are those calculated by the software described in section 3.2.8.
All register settings are default, except for those stated in the relevant sub-sections
Maximum Output Power programmed on Pout tests
All sensitivities are evaluated in Continuous mode, demodulating a PN15 sequence, BER=0.1%
FSK sensitivities measured at 25kbps, Fdev=+/-50 kHz
OOK sensitivities measured at 8kbps, with Fo=100 kHz. IF2 set to 100 kHz.
On all Adjacent Channel Rejection (ACR), Blocking and Spurious Response Frequency tests, the unwanted
signal is unmodulated.
Bill of Materials as shown in section 7.5.3. In particular, a SAW filter is used (see its performance on section
7.5.4)
The filter settings described on Table 37 and Table 38 were used for the measurements of section 7.6.5.
