DESCRIPTION
The TRF1121/TRF1221 are VHF-UHF upconverters
with
integrated
UHF
synthesizers for radio applications in the 2GHz to 4
GHz range. The IC performs the first up-conversion
and generates the local oscillator (LO) for the second
up-conversion. The device uniquely integrates an
image reject mixer, IF gain blocks, 5-bit gain control,
and two complete phase locked loop (PLL) circuits
including: VCOs, resonator circuit, varactors, dividers,
and phase detectors.

SLWS170A–APRIL 2005–REVISED DECEMBER 2005
Dual VCO/PLL Synthesizer With IF Up-Converter
The TRF1121/TRF1221 are designed to function as
part of complete 2.5-GHz and 3.5-GHz radio chipsets,
respectively.
In
the
chipset,
operates as a double up converter from an IF
frequency input (typically from a baseband modem's
DAC) to an RF output frequency. The TRF1121/
TRF1221 performs the first up conversion from IF
signals in the range of 10 MHz to 60 MHz to a
second IF frequency in the range of 300 MHz to 360
MHz. The radio chipset features sufficient linearity,
phase noise, and dynamic range to work in either
single
carrier
or
multi-carrier,
non-line-of-sight,
standard
proprietary systems. Due to the modular nature of the
chipset, it is ideal for use in systems that employ
transmit or receive diversity.
