HMC584LP5E

The HMC584LP5E by Hittite Microwave Corporation is a Monolithic Microwave Integrated Circuit (MMIC) Voltage Controlled Oscillator (VCO) designed for RF applications. This device integrates resonators, negative resistance devices, and varactor diodes, offering both a primary frequency (Fo) output and a half-frequency (Fo/2) output. It also includes a divide-by-4 function.

Key electrical specifications include a frequency range of 12.5 to 13.9 GHz for Fo and 6.25 to 6.95 GHz for Fo/2. The typical output power is +10 dBm for the main RF output. The VCO boasts excellent phase noise performance, rated at -110 dBc/Hz at a 100 kHz offset. It operates from a +5V supply voltage.

The HMC584LP5E is designed for applications such as point-to-point and multipoint radio systems, test equipment, industrial controls, SATCOM, and military end-use. Its monolithic structure ensures excellent performance over temperature, shock, and process variations. The prescaler and RF/2 functions can be disabled to conserve current when not needed.

Packaged in a 32-lead 5x5mm QFN surface mount package, the HMC584LP5E requires no external matching components, simplifying board design and assembly. The compact 25mm² footprint makes it suitable for space-constrained applications.
