General Description
The HMC447LC3 is a low noise Divide-by-4 Regen-
erative 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) dis-
tribution 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.
