Note 1:
All limits include external component losses. Output measurements taken at RFOUT or LBOUT ports of the
Typical
Application Circuit
.
Note 2:
Operating outside this range is possible, but with degraded performance of some parameters.
Note 3:
Compression point characterized. It is advisable not to continuously operate the VGA RF input above +15dBm.
Note 4:
Input RF source contribution to spurious emissions (Agilent ESG 4435B, PSA E4443A): 200kHz = -39.2dBc,
400kHz = -73.5dBc, 600kHz = -83.2dBc, 1.2MHz = -85.7dBc
Note 5:
See the
Applications Information
section regarding effective attenuation range.
Note 6:
No SPI clock input applied.
Note 7:
Guaranteed by design and characterization.
