ALM-1222
1.8-2.2GHz Noise, High Gain, High Linearity Balanced Amplifier Module
Avago Technologies' ALM-1222 very noise, high linearity balanced amplifier module operating 2.2GHz frequency range. exceptional noise linearity performances achieved through Avago Technologies' proprietary 0.5um GaAs Enhancement-mode pHEMT process. matching components fully integrated within module input output pins already internally AC-coupled. This makes ALM1222 extremely easy only external parts supply bypass capacitors. ALM-1222 housed miniature 22-lead multiple-chips-on-board (MCOB) module package. compact footprint profile makes this product ideal choice Wireless Infrastructure Basestation Tower-Mounted Amplifiers (TMA), Radiocards Multi-Carrier Driver Amplifiers cellular/PCS/CDMA bands.
