ALM-31122

ALM-31122 700MHz - 1GHz 1-Watt High Linearity Amplifier Data Sheet Description Avago Technologies’ ALM-31122 is a high linearity 1 Watt PA with good OIP3 performance and exceptionally good PAE at 1dB gain compression point, achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. All matching components are fully integrated within the module. This makes the ALM-31122 extremely easy to use. The adjustable temperature-compensated internal bias circuit allows the device to be operated at either class A or class AB operation. The ALM-31122 is housed inside a miniature 5.0 x 6.0 x 1.1 mm3 22-lead multiple-chips-on-board (MCOB) module package.
