HMC703LP4E

The HMC703LP4E is an 8 GHz fractional synthesizer IC from Analog Devices, built on a high-performance PLL platform. It offers a wide frequency range from DC to 8 GHz for its RF input. This device boasts industry-leading phase noise performance of -112 dBc/Hz at an 8 GHz fractional offset of 50 kHz, and a figure of merit of -230 dBc/Hz in fractional mode.

Key features include a high PFD rate of 100 MHz and low RMS jitter of less than 50 fs. The HMC703LP4E supports frequency and phase modulation, an integrated frequency sweeper, and triggered frequency hopping. It operates over a temperature range of -40°C to 85°C and requires a voltage supply between 2.7V and 5.5V.

Packaged in a 24-QFN (4x4) surface mount configuration, this synthesizer is suitable for demanding applications. Its exact frequency mode with a 24-bit fractional modulator enables fractional frequencies with zero error and low channel spurious, making it valuable for Digital Pre-Distortion systems. The serial interface provides read-back capability.

Typical applications include microwave point-to-point radios, base stations for mobile radio (GSM, PCS, DCS, CDMA, WCDMA), wireless LANs, WiMAX, communications test equipment, CATV equipment, automotive sensors, phased arrays, and FMCW radar systems.
