Dual PLL/VCO With IF Down-Converter

The TRF1112 / TRF1212 are UHF-VHF Down Converters with integrated UHF and S-band Frequency Synthesizers for Radio applications in the 2GHz to 4GHz 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.
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.
