Designing with the MA02303GJ

The MA02303GJ is built using a near-enhancement mode FET that operates from a single supply voltage. A negative

voltage is not required because the FET is designed to operate with a +0V DC gate bias.

There is no impedance matching or RF choking on this IC – these functions are supplied externally. This approach

offers the highest level of performance, the lowest bill of materials cost, and far fewer components than a discrete de-

sign.

To duplicate MA02303GJ data sheet performance, your circuit board must recreate the same impedances developed on

this evaluation board. The table below has one-port s-parameter measurements looking into the traces on the evalua-

tion board. S-parameters of the MA02303GJ are not supplied because the device is designed to operate under large-

signal conditions.
