10-16GHz Low Noise Amplifier
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
N°2 : Not biased in such a way that Vgs becomes positive.
We propose two standard biasing :
Low Noise and low consumption :
( Equivalent to A,B,C,D,E : NC and Vd=4V ; G1=+1.4V ; G2=+1.4V).
Low Noise and high output power :
( Equivalent to A,B,C,D,E : NC and Vd=5V ; G1=+1.4V ; G2=+4.0V).
A file is available on request to help the biasing option tuning.
