ALM-1222-TR1G

ALM-1222 1.8-2.2GHz Low Noise, High Gain, High Linearity Balanced Amplifier Module Data Sheet Description Features Avago Technologies’ 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 Avago Technologies’ proprietary 0.5um GaAs Enhancement-mode pHEMT process. • Low noise figure 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 Basestation Tower-Mounted Amplifiers (TMA), Radiocards and Multi-Carrier Driver Amplifiers in the cellular/ PCS/CDMA bands.

Distribution data sample size is 500 samples taken from 3 different wafers and 3 different lots. Future wafers allocated to this product may have nominal values anywhere between the upper and lower limits. 6. Measurements are made on a production test board, which can show a variance of up to 1dB in gain and OIP3 compared to a soldered-down demo board. Input trace losses have been de-embedded from actual measurements. 2 Electrical Specifications [7], [10] TA = 25 °C, Vdd =5V @ 280mA, RF performance at 2.0 GHz, given for each of the 2 RF paths, measured on demo board (see Fig. 5) unless otherwise specified.
