Note 1: Min and max values are production tested at T
A
= +25°C and +85°C. Min and max limits at T
A
= -40°C are guaranteed by
design and characterization. Default register settings are not production tested; load all registers no sooner than 100µs
after power-up.
Note 2: In-band IIP3 is measured with two tones at f
LO
- 100kHz and f
LO
- 200kHz at a power level of -23dBm/tone. GC1 is set for
maximum attenuation (V
GC1
= 2.7V) and GC2 is adjusted to achieve 250mV
P-P
/tone at the I/Q outputs for an input desired
level of -23dBm.
Note 3: Out-of-band IIP3 is measured with two tones at f
RF
+ 6MHz and f
RF
+ 12MHz at a power level of -15dBm/tone. GC1 is set
for maximum attenuation (V
GC1
= 2.7V) and GC2 is adjusted to achieve 0.5V
P-P
at the I/Q outputs for an input desired level
of -50dBm. f
RF
is set to 767MHz + 1/7MHz = 767.143MHz.
Note 4: GC1 is set for maximum attenuation (V
GC1
= 2.7V). GC2 is adjusted to give the nominal I/Q output voltage level (0.5V
P-P
)
for a -50dBm desired tone at f
RF
= 550MHz. Two tones, 220MHz and 770MHz at -15dBm/tone, are then injected and the
571kHz IM2 levels are measured (with a 550.571MHz LO) at the I/Q outputs and IP2 is then calculated.
Note 5: Guaranteed by design and characterization.
Note 6: Guaranteed and tested at T
A
= +25°C and +85°C only.
