TRF3761-FIRHAR TI PLL/VCO | 40-VQFN (6x6) | 3.0-4.4GHz, Low Phase Noise

Product Overview

The TRF3761-FIRHAR from Texas Instruments is a high-performance, fully integrated fractional-N phase-locked loop (PLL) and voltage-controlled oscillator (VCO) designed for demanding RF applications. Operating from 3.0 to 4.4 GHz, this device delivers exceptional phase noise performance of -110 dBc/Hz at 10 kHz offset (carrier at 3.6 GHz) and -140 dBc/Hz at 1 MHz offset. The integrated VCO eliminates the need for external resonator components, simplifying design and reducing board space. Housed in a compact 40-pin VQFN (6x6 mm) package, it is ideal for space-constrained applications.
