Description
The LMX2594RHAR is a high-performance, wideband RF synthesizer from Texas Instruments, designed for applications requiring low phase noise and fast frequency switching. Key features include:
- Frequency Range: 20 MHz to 15 GHz (with internal doubler).
- Low Phase Noise: Optimized for radar, 5G, and test equipment.
- Integrated VCO: Eliminates external VCO, reducing design complexity.
- High Resolution: 32-bit fractional-N divider for fine frequency steps.
- Fast Switching: <25 µs for critical timing applications.
- SPI Interface: Easy configuration with a microcontroller.
Applications include wireless infrastructure, aerospace, and instrumentation. The device operates from 3.15V to 3.45V and comes in a 40-pin QFN (RHA) package.
For detailed specs, refer to the [TI datasheet](https://www.ti.com/lit/ds/symlink/lmx2594.pdf).
