18-31GHz Low Noise Amplifier
GaAs Monolithic Microwave IC
Description
The circuit is a three-stage self biased
wide band monolithic low noise amplifier.
The circuit is manufactured with a standard
HEMT process : 0.25µm gate length, via
holes through the substrate, air bridges
and electron beam gate lithography.
It is supplied in chip form.

Typical Chip Assembly
Chip Biasing options
This chip is self-biased, and flexibility is provided by the access to number of pads. the
internal DC electrical schematic is given in order to use these pads in a safe way.
The two requirements are :
N°1 : Not exceed Vds = 3.5Volt ( internal Drain to Source voltage ).
N°2 : Not biased in such a way that Vgs becomes positive.
( internal Gate to Source voltage )
We propose two standard biasing :
Low Noise and low consumption :
Vd = 4.5V and B, D, E grounded.
All the other pads non connected ( NC ).
Idd = 55mA & Pout-1dB = 10dBm Typical.
( Equivalent to A,B,C,D,E F: non connected and Vd=4.5V ; G1=G2=G3=+1.V ).
Low Noise and higher output power
Vd = 4.5V and B, C, F grounded.
All the other pads non connected ( NC ).
Idd = 75mA & Pout-1dB = 12dBm Typical..
