Avago Technologies has a pair of very low-noise, high-linearity, high-gain balanced amplifier modules that operate in the 1.8- to 2.2-GHz frequency range. Housed in a small package (5.0 6.0 1.1mm), they are ideal for diversity antennas, tower-mounted amplifiers (TMAs), and front-end, low-noise amplifiers in macro-cell, micro-cell and picocell cellular base stations and repeaters.
The LNAs’ performance characteristics meet the requirements for the extended global system for mobile communications (EGSM), GSM, personal communications system (PCS), and wideband code division multiple access (W-CDMA) networks.
The ALM-1222 and ALM-1322 reduce system noise figure and out-ofband frequency response in high signal-level areas. They are fully matched to 50Ω to simplify system design and minimize the number of external components. Their small 22-lead multiple-chip-on-board (MCOB) module package reduces PC board dimensions.
