1 The transmit current consumption tests used the same combined PA and LNA matching network as that used on the EVAL-ADF7021DBx evaluation boards. Improved
PA efficiency is achieved by using a separate PA matching network.
TIMING CHARACTERISTICS
VDD = 3 V ± 10%, DGND = AGND = 0 V, TA = 25°C, unless otherwise noted. Guaranteed by design but not production tested.
