SLWS170B–APRIL 2005–REVISED JANUARY 2008  
Dual VCO/PLL Synthesizer With IF Upconverter  
The TRF1121 and TRF1221 are designed to function  
as part of complete 2.5-GHz and 3.5-GHz radio  
chipsets, respectively. In the chipset, the transmit  
chain operates as a double upconverter from an IF  
frequency input (typically from a baseband modem's  
DAC) to an RF output frequency. The TRF1121/  
TRF1221 performs the first upconversion 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 multicarrier, line-of-sight or  
non-line-of-sight, standard (IEEE 802.16), or  
proprietary systems. Due to the modular nature of the  
chipset, it is ideal for use in systems that employ  
transmit or receive diversity.

DESCRIPTION  
LF1  
LD1  
The TRF1121 and TRF1221 are VHF-UHF  
upconverters with integrated UHF and S-band  
frequency synthesizers for radio applications in the  
2-GHz to 4-GHz range. The IC performs the first  
upconversion and generates the local oscillator (LO)  
for the second upconversion. 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.
