CHA2069-FAA
16-32GHz Low Noise Amplifier
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.
Vd
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:
Low Noise and higher output power
Vd = 4.5V and B, D, E grounded.
All the other pads non connected (NC).
Idd = 55mA & Pout-1dB = 10dBm Typical.
Vd = 4.5V and B, C, F grounded.
All the other pads non connected (NC).
Idd = 75mA & Pout-1dB = 12dBm Typical.
