Analog Devices Inc. ADF4355BCPZ Wideband Frequency Synthesizer
The ADF4355BCPZ from Analog Devices Inc. is a high-performance, integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO) designed for wideband frequency synthesis. Housed in a compact 32-lead LFCSP (5 mm × 5 mm) package, this device operates across a broad frequency range of 2200 MHz to 4400 MHz, supporting applications requiring precision signal generation. It features a flexible power supply range of 3.15 V to 3.45 V and operates over an industrial temperature range of -40°C to +85°C. With its integrated fractional/integer-N PLL architecture, low phase noise, and programmable output power, the ADF4355BCPZ is ideal for wireless communication, test equipment, and radar systems.
ADF4355BCPZ Features
The ADF4355BCPZ delivers industry-leading phase noise performance (-110 dBc/Hz at 100 kHz offset) and ultra-fast frequency switching (20 µs typical), critical for agile frequency-hopping systems. Its integrated VCO eliminates external components, simplifying design and reducing board space. The device supports multiple output modes, including RF output power adjustment from -4 dBm to +5 dBm, and offers a programmable dual-modulus prescaler for flexible frequency resolution. Additional features include a 25-bit fixed modulus fractional-N interpolator, reference doubler, and cycle slip reduction, ensuring stability in demanding environments.
ADF4355BCPZ Applications
This synthesizer is widely used in wireless infrastructure (5G, LTE, and microwave backhaul), satellite communication systems, and military/aerospace radar. Its precision makes it suitable for automated test equipment (ATE), spectrum analyzers, and frequency-hopping spread spectrum (FHSS) applications. The ADF4355BCPZ also supports software-defined radios (SDRs), point-to-point radios, and local oscillator (LO) generation in phased-array systems, where high frequency accuracy and low jitter are critical.
ADF4355BCPZ Selection Advantages
The ADF4355BCPZ stands out for its combination of wide frequency coverage, low phase noise, and integration, reducing BOM costs and design complexity. Compared to discrete PLL-VCO solutions, it offers superior phase noise performance and faster lock times. Its compatibility with Analog Devices’ ACE software simplifies frequency planning and register configuration. Engineers benefit from its robust ESD protection (2 kV HBM) and industrial-grade reliability, ideal for mission-critical systems.
