FREQUENCY DIVIDERS & DETECTORS - SMT
4 - 1
General Description
Features
Functional Diagram
The HMC438MS8G & HMC438MS8GE are low noise
Divide-by-5 Static Dividers utilizing InGaP GaAs
HBT technology in low cost 8 lead surface mount
plastic packages. This device operates from DC
(with a square wave input) to 7 GHz input frequency
from a single +5V DC supply. The low additive SSB
phase noise of -153 dBc/Hz at 100 kHz offset helps
the user maintain good system noise performance.
SSB Phase Noise: -153 dBc/Hz @100 kHz
Wide Bandwidth
Output Power: -1 dBm
Single DC Supply: +5V @ 80 mA
