Functional Diagram
General Description
The HMC447LC3 is a low noise Divide-by-4
Regenerative Divider utilizing InGaP GaAs HBT
technology. This wideband divider operates with input
frequencies from 10 to 26 GHz, and accepts a very wide
range of input power levels. THe HMC447LC3 exhibits
a very low SSB Phase Noise of -150 dBc/Hz at 100 kHz
offset, making it ideal for use in high frequency Phase
Locked Loops (PLL), and in Local Oscillator (LO)
distribution applications where fundamental and
divided LO frequencies are required within a
system. This versatile divider consumes only 96 mA
from a single positive supply of +5V, and delivers
very flat output power across the rated bandwidth.
The HMC447LC3 is housed in a RoHS compliant,
3x3 mm leadless SMT package with an exposed
ground paddle.
