The HMMC-5025 was designed as a generic wide band
distributed amplifier, covering the frequency span 2–
50 GHz. It consists of seven stages. Each stage is made
up of two cascoded FETs with gate peripheries of 48
µm per FET. Both input and output ports were
designed to provide 50 Ohm terminations. Bonding
pads are provided in the layout to allow amplifier
operation at frequencies lower than 2 GHz by means
of external circuit components.
The amplifier is biased with a single positive drain
supply (VDD) and a single negative gate supply (VG1).
A second date connection is provided for external
gain control applications.
