Functional Diagram
General Description
The HMC437MS8G & HMC437MS8GE are low noise Divide-by-3 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.
Electrical Specifications, TA = +25° C, 50 Ohm System, Vcc= 5V
