LMX2595RHAT General Description

The LMX2595RHAT is a high-performance RF synthesizer with integrated VCO (voltage-controlled oscillator) designed for applications in wireless infrastructure, instrumentation, and aerospace systems. It operates over a frequency range of 10 MHz to 26.5 GHz and offers low phase noise and high output power.The device features a fractional-N PLL (phase-locked loop) architecture with a 34-bit delta-sigma modulator, enabling precise frequency synthesis with fine resolution. It also includes an internal loop filter, allowing for simplified system design and reduced external component count.The LMX2595RHAT is housed in a compact 48-pin VQFN package, making it suitable for space-constrained applications. It operates from a single 3.3 V supply and consumes low power, making it ideal for battery-operated devices.
