CHA2193
RoHS COMPLIANT
20-30GHz Low Noise Amplifier
GaAs Monolithic Microwave IC Description
The CHA2193 is a three stages low noise amplifier. It is designed for a wide range of applications, from military to commercial communication systems. The backside of the chip is both RF and DC grounds. This helps simplify the assembly process. The circuit is manufactured with a HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography. It is available in chip form.

Typical Bias Tuning for Low Noise Operation
For low noise operation, a separate access to the gate voltages of the first stage ( Vgs1 ), and of the second and third stages ( Vgs2 ) is provided. Nominal bias for low noise operation is obtained for a typical current of 20 mA for the second and third stages and 10 mA for the first stage ( 50 mA for the amplifier ). The first step to bias the amplifier is to tune the Vgs1 = -1V, and Vgs2 to drive 40 mA for the full amplifier. Then Vgs1 is reduced to obtain 50 mA of current through the amplifier. A fine tuning of the noise figure may be obtained by modifying the Vgs1 bias voltage, but keeping the previous value for Vgs2.
