HMC703LP4ETR

The HMC703LP4ETR is an 8 GHz fractional synthesizer IC designed for high-performance applications. Built on a robust PLL platform, it delivers industry-leading phase noise and spurious performance, enabling higher-order modulation schemes and minimizing blocker effects in radio systems.

Key electrical specifications include a wide band RF input from DC to 8 GHz, a phase noise of -112 dBc/Hz at 8 GHz with a 50 kHz offset, and a high PFD rate of 100 MHz. It also features < 50 fs RMS jitter, frequency and phase modulation capabilities, an integrated frequency sweeper, and triggered frequency hopping.

This device supports both Integer-N and Fractional-N synthesis, with an exact frequency mode utilizing a 24-bit fractional modulator for zero frequency error and very low channel spurious. The HMC703LP4ETR operates over a temperature range of -40°C to 85°C and requires a supply voltage between 2.7V and 5.5V.

The HMC703LP4ETR is supplied in a compact 24-lead 4x4 mm Surface Mount package (24-QFN Exposed Pad). Its serial interface offers read-back capability and is compatible with various protocols. This synthesizer is ideal for microwave point-to-point radios, base stations, wireless LANs, WiMAX, communications test equipment, CATV equipment, automotive sensors, phased arrays, and FMCW radar systems.
