DEVICE INFORMATION
DESCRIPTION
The TRF1112 / TRF1212 are UHF-VHF down con-
verters with integrated UHF and S-band frequency
synthesizers for radio applications in the 2 GHz to 4
GHz range. The device integrates an image reject
mixer, IF gain blocks, automatic gain control (AGC),
and two complete phase locked loop (PLL) circuits
including: VCOs, resonator circuit, varactors, dividers,
and phase detectors.

SLWS175–APRIL 2005
3.5-GHz Integrated IF Up-Converter
The TRF1112 / TRF1212 are designed to function as
part of Texas Instruments 2.5-GHz and 3.5-GHz
complete radio chipsets, respectively. In the chipset,
two chips function together to double-down-convert
RF frequencies to an IF frequency that is suitable for
most baseband modem ADCs. The TRF1112 /
TRF1212 performs the second down conversion from
the first IF frequency (480 MHz typical) to a final IF
frequency (20-50 MHz). The radio chipset features
sufficient linearity, phase noise and dynamic range to
work in single carrier or multi-carrier, line-of-sight or
non-line-of-sight, IEEE standard 802.16, BWIF, or
proprietary systems. Due to the modular nature of the
chipset, it is ideal for use in systems that employ
transmit or receive diversity.
