Note 1:
Min/max values are production tested at T
A
= +70°C. Min/max limits at T
A
= 0°C and T
A
= +25°C are guaranteed by design
and characterization.
Note 2:
Gain-control range specifications met over this band.
Note 3:
In-band IIP3 test conditions: GC1 set to provide the nominal baseband output drive when mixing down a -23dBm tone at
2175MHz to 5MHz baseband (f
LO
= 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-26dBm each are applied at 2174MHz and 2175MHz. The IM3 tone at 3MHz is measured at baseband, but is referred to the
RF input.
Note 4:
Out-of-band IIP3 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at
2175MHz to 5MHz baseband (f
LO
= 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at
-20dBm each are applied at 2070MHz and 1975MHz. The IM3 tone at 5MHz is measured at baseband, but is referred to the
RF input.
Note 5:
Input IP2 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at 2175MHz
to 5MHz baseband (f
LO
= 2170MHz). Baseband gain is set to its default value (BBG[3:0] = 1011). Two tones at -20dBm
each are applied at 925MHz and 1250MHz. The IM2 tone at 5MHz is measured at baseband, but is referred to the RF input.
Note 6:
Adjacent channel protection test conditions: GC1 is set to provide the nominal baseband output drive with a 2110MHz
27.5Mbaud signal at -55dBm. GC2 set for mid-scale. The test signal will be set for PR = 7/8 and SNR of -8.5dB. An adjacent
channel at ±40MHz is added at -25dBm. DVB-S BER performance of 2E-4 will be maintained for the desired signal. GC2
may be adjusted for best performance.
Note 7:
Guaranteed by design and characterization at T
A
= +25°C.
