HMC830LP6GE
v03.0512
FRACTIONAL-N PLL WITH INTEGRATED VCO
25 - 3000 MHz
General Description
The HMC830LP6GE is a low noise, wide band, Fractional-N Phase-Locked-Loop (PLL) that features an integrated
Voltage Controlled Oscillator (VCO) with a fundamental frequency of 1500 MHz - 3000 MHz, and an integrated VCO
Output Divider (divide by 1/2/4/6.../60/62), that together allow the HMC830LP6GE to generate frequencies from
25 MHz to 3000 MHz. The integrated Phase Detector (PD) and delta-sigma modulator, capable of operating at up to
100 MHz, permit wider loop-bandwidths with excellent spectral performance.
The HMC830LP6GE features industry leading phase noise and spurious performance, across all frequencies, that
enable it to minimize blocker effects, and improve receiver sensitivity and transmitter spectral purity. The superior
noise oor (< -170 dBc/Hz) makes the HMC830LP6GE an ideal source for a variety of applications - such as; LO for
RF mixers, a clock source for high-frequency data-converters, or a tunable reference source for ultra-low spurious
applications.
Additional features of the HMC830LP6GE include RF output power control from 0 to 9 dB (3 dB steps), output Mute
function, and a delta-sigma modulator Exact Frequency Mode which enables users to generate output frequencies
with 0 Hz frequency error.
