Buffer Amplifier

Mimix Broadband's CMM-9 is a 2 to 9 GHz GaAs MMIC
amplifier. It is a two-stage feedback design which provides
high gain and good power from a single power supply.
Applications include oscillator buffers, RF and IF gain blocks
and driver amplifiers.
The CMM-9 is a very small chip which provides 13 dB of gain
and 17 dBm of power from a 6 volt supply. The chip is
directly cascadable with no additional components. The
circuits self-biasing feature provides excellent performance
from a 5 to 7 volt supply. Care must be taken to isolate the
input from the external DC voltages.
Mimix MMICs are fabricated on ion-implanted GaAs material
with gold-based metalization. The FET gates are sub-half
micron, tee cross-section construction. Air bridges are used
for top level interconnection. Silicon nitride serves as
capacitor dielectric and surface passivation. Mesa resistors
are used for feedback and bias function.
The CMM-9 is available in chip form. It can be screened to
meet commercial, military Hi-Rel or space grade reliability
requirements. Custom wafer qualification for special
electrical and/or reliability requirements is also available.
