Conditions

TEMPERATURE °C

282 Mitel characterisation board (Fig. 5), fC = 282MHz

1200bps baud rate, 4kHz peak deviation frequency, BER 1 in 30

The LNA gain is set such that an RF signal of 273dBm at the LNA input, offset from the LO by 4kHz, gives a typical signal

level of 300mVp-p at TPI and TPQ
