ELECTRICAL CHARACTERISTICS (continued)
Test conditions (unless otherwise stated)
Tamb= 0oC to 85oC,
*
Vee= 0V, Vcc = 4.75 to 5.25 V, Fif = 479.5 MHz, IF bandwidth +- 22 MHz
These characteristics are guaranteed by either production test or design. They apply within the specified ambient temperature
and supply voltage unless otherwise stated.

Performance not guaranteed over full specified IF input operating range
I Q crosstalk is determined from the gain and phase match by the following formula
Crosstalk = 20* Log (tan(phase error + Atan (1+amplitude imbalance) -45
°
))
Over specified gain dynamic, 1k
load up to 22MHz baseband
Over specified gain dynamic range, 1k
load up to 30MHz baseband
Baseband bandwidth 0.1 to 22MHz
The device should not be operated beyond the point of output clipping. The quality and amplitude of the
baseband output signals cannot be guaranteed once this level has been exceeded.
*
Operating temperature range for the SL1711B is 0
°
C to 70
°
C. This applies to applications featuring a double
sided copper board. For other applications not using such a board, the maximum operating
temperature may be reduced.
The above device characteristics are guaranteed provided the output is maintained below the onset of clipping.
