Product Summary
The TRF1221IRGZT is a VHF-UHF up converter with integrated UHF and S-band frequency synthesizers for radio applications in the 2GHz to 4GHz range. The IC performs the first up-conversion and generates the local oscillator (LO) for the second up-conversion. The TRF1221IRGZT 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.
