PARAMETER
Note 1:
All specifications with guaranteed min/max limits are met within this frequency range. Contact factory for
MAX2102/MAX2105 versions with expanded frequency range.
Note 2:
Guaranteed by production test and/or design and characterization.
Note 3:
Guaranteed by design and characterization.
Note 4:
IOUT, QOUT Phase and Amplitude Imbalance specifications are met within this LO power range.
Note 5:
Tested under two conditions: 1) Normal test: P
RFIN
= -20dBm, and 2) Overdrive test: P
RFIN
= -5dBm but AGC set via servo
loop for V
IOUT
= V
QOUT
= 0.5Vp-p for P
RFIN
= -30dBm.
Note 6:
Negative numbers (-0.1°) indicate improvement in quadrature accuracy with increasing temperature.
Note 7:
Includes contribution from front-end gain tilt and delay variations produced by varying f
RFIN
by ±30MHz.
Note 8:
1kHz minimum frequency determined by 0.22μF offset-correction capacitors. Different value capacitors yield proportionally
different low-frequency cutoffs. Group delay at low frequencies will also be affected. See Applications Informationsection.
