General Description
The HMC426MS8 & HMC426MS8E are low noise
Divide-by-4 Static Dividers utilizing SiGe technology
in 8 lead surface mount plastic packages. This
device operates from DC (with a square wave input)
to 4.0 GHz input frequency while operating from a
single +3V supply at only 13 mA. The low additive
SSB phase noise of -146 dBc/Hz at 100 kHz offset
helps the user maintain excellent system noise
performance.
