LMX2572RHAR

The LMX2572RHAR is a high-performance, low-power RF synthesizer from Texas Instruments, designed for wireless communication systems. It integrates a PLL (Phase-Locked Loop) and VCO (Voltage-Controlled Oscillator) with a frequency range of 20 MHz to 3.7 GHz, supporting fractional-N and integer-N modes.
Key features include:
- Ultra-low jitter for high signal integrity.
- Programmable output power (up to +5 dBm).
- SPI interface for easy configuration.
- Low power consumption (~40 mA typical).
Applications include 5G, IoT, radar, and test equipment. Its compact 40-pin QFN (RHA) package makes it suitable for space-constrained designs.
The LMX2572RHAR offers excellent phase noise performance, making it ideal for demanding RF applications.
