UMS CHA3023 1-18 ghz wide band amplifier Datasheet

CHA3023
RoHS COMPLIANT
1-18 GHz WIDE BAND AMPLIFIER
GaAs Monolithic Microwave IC
Description
The CHA3023 is a travelling wave amplifier
using cascode FET. It is designed for a wide
range of applications.
The circuit is manufactured with a PHEMT
process of 0.25µm gate length, via holes
through the substrate and air bridges and it
is available in die form.

The CHA3023 could be used without Vg2 bias. There is a resistor bridge inside the chip. This
one generates the correct value of Vg2 Bias. Pads G2a and G2 must be connected.
Equivalent RF Wire Bondings: 0.15 nH (typical length of 200µm for a 25µm diameter wire).
