High current Infinity probe for power RF devices
The rapid growth of wireless voice and data traffic has resulted in demand for more RF power devices in both handsets and wireless system infrastructure. The design of RF power devices and linear power amplifiers that use them requires measurements of gain, linearity, and efficiency under various load conditions to optimize circuit designs. During characterization, transistor performance is established by varying source and load impedance. Cascade Microtech’s new high-current Infinity probe allows designers to model transistors under load conditions at up to 2 amperes, while maintaining low contact resistance (typically < 0.05 ohm on aluminum pads).
