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.
