Total supply current:
Power supply range (transceiver Vcc)
Operating temperature range
Note 1: Gain steps are such that monotonicity is maintained throughout the entire IF gain range.
Note 2: Specified down to 2.8 V supply voltage. Slight degradation at temperature extremes for 2.7 V supply voltage.
Note 3: Refer to Figure 7 for the 1 dB compression point of the entire receiver chain, including the baseband gain section.
Note 4: For 1 Vp-p 100 kHz differential signals acorss lin and Qin.
Note 5: Using transmit VCO with similar characteristics as Murata MQE 550-902.
Note 6: Using varactors with similar characteristics as Alpha part SMV1234-004.
Note 7: Refer to Figure 6.
