ALM-1222 is a very low noise, high linearity balanced amplifier module operating in the 1.8 to 2.2GHz frequency range. The exceptional noise and linearity performances are achieved through the use of proprietary 0.5um GaAs Enhancement-mode pHEMT process. All matching components are fully integrated within the module and the 50Ω RF input and output pins are already internally AC-coupled. This makes the ALM-1222 extremely easy to use as the only external parts are DC supply bypass capacitors. The ALM-1222 is housed in a miniature 5.0 x 6.0 x 1.1 mm3 22-lead multiple-chips-on-board (MCOB) module package. The compact footprint and low profile makes this product an ideal choice for Wireless Infrastructure base station Tower-Mounted Amplifiers (TMA), Radiocards and Multi-Carrier Driver Amplifiers in the cellular/PCS/CDMA bands.
