ISET Pins
ISET1 sets the internal reference voltage for the bias control circuits to all functional blocks. An external resistor of 4.3k
to ground is recommended. We do not recommend adjusting this resistor value. This resistor is pulled out to allow for a
higher precision off chip value and not as a significant tuning adjustment.
ISET2 sets the DC current through the mixer and mixer preamplifier. Higher resistance to ground results in lower current.
Lower current will improve mixer NF but will degrade IIP3. Mixer and the mixer preamp gain is not significantly changed
with current.
