Conditions

Standard Mitel characterisation board (Fig. 5)

ICC1 includes IRF LNA current (typ. 500µA) but does not include the regulator load current

The Audio AGC and RF AGC are both inactive

ICC2 is measured with BATTFLAG and DATAS OP high, fC = 282MHz

Conditions

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
