3.0 V 100 mW RF Power Amplifier IC for Bluetooth
Designing With the MA02305AK
MA02305AK
V 1.00
The MA02305AK is built using a near-enhancement mode FET that operates from a single supply voltage. A nega-
tive 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.
To duplicate MA02305AK data sheet performance, your circuit board must recreate the same impedances developed
on the evaluation board depicted in the preceding figures. One-port S-parameters looking into the board impedances
away from the device are listed below. The calibration plane for the datasheet is the pin of the device.
