12.5-30GHz Low Noise Amplifier
CHA3689-99F
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 requirement is not to exceed Vds = 3.5Volt (internal Drain to Source voltage ).
We propose two standard biasings:
Low Noise and low consumption:
Vd = 4V and B, D not connected (NC).
Idd = 90mA & Pout-1dB = 14dBm Typical
Low Noise and higher output power: Vd = 4V and B, D grounded.
Idd = 120mA & Pout-1dB = 15dBm Typical
