RF Power Amplifier IC For 2.5 GHz ISM Designing with the MA02303GJ MA02303GJ V7 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 design. 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 evaluation board. S-parameters of the MA02303GJ are not supplied because the device is designed to operate under large-signal conditions.
