Description
Agilent’s AMMC-6241 is a high
gain, low-noise amplifier that
operates from 26 GHz to 43
GHz. This LNA provides a
wide-band solution for system
design since it covers several
bands, thus, reduces part
inventory. The device has
input / output match to 50
Ohm, is unconditionally stable
and can be used as either
primary or sub-sequential low
noise gain stage. By
eliminating the complex tuning
and assembly processes
typically required by hybrid
(discrete-FET) amplifiers, the
AMMC-6241 is a cost-effective
alternative in the 26 - 43 GHz
communications receivers. The
backside of the chip is both
RF and DC ground. This helps
simplify the assembly process
and reduces assembly related
performance variations and
costs. It is fabricated in a
PHEMT process to provide
exceptional noise and gain
performance. For improved
reliability and moisture
protection, the die is
passivated at the active areas.

Note: Operation in excess of any one of these conditions may result in permanent damage to this device.
Note: These devices are ESD sensitive. The following precautions are strongly recommended. Ensure that an ESD approved
carrier is used when dice are transported from one destination to another. Personal grounding is to be worn at all times when
handling these devices. For more details, refer to Agilent Application Note A004R: Electrostatic Discharge Damage and Control.
