General Description
The TQP519021 is a high-linearity dual-channel down-
converter designed to meet the demanding performance,
functionality, and cost goals of current and next
generation mobile infrastructure base-stations. It provides
high dynamic range performance in a low profile lead-
free/RoHS-compliant surface-mount leadless package
that measures 6x6 mm square.
The TQP519021 is a fully integrated diversity mixer
that includes LO switch, two stage LO drivers, high-
linearity mixers, RF balun and IF amplifiers. The IF
amplifiers can be set to standard current or low current
mode through logic input pins. The TQP519021 also
integrates power down feature controlled by separate
logic pin.
The TQP519021 is designed to provide 9 dB conversion
gain, +25.5 dBm Input IP3, +11.8 dBm Input P1dB and a
noise figure of 10.8 dB over the 680-920MHz frequency
range for diversity receiver applications. TQP519021 is
optimized for low side LO application but also works for
High-side LO applications with slightly degraded
linearity performance. The TQP519021 is footprint and
pin compatible with TriQuint’s 1.7-2.2 GHz TQP569022
mixer for high band applications.
