The company’s ALM-1522, which is the new addition to its ALM-1×22 family of economical, easy-to-use fully matched GaAs amplifiers, is ideal for major 800 MHz / 900 MHz cellular bands such as GSM, CDMA, UMTS and new Long Term Evolution (LTE) applications that operate in the 700 MHz band.
The exceptional noise and linearity performance offered by this balanced amplifier module is achieved through the use of company’s new 0.25 µm GaAs Enhancement-mode pHEMT process. Housed in a miniature 5mm by 6mm by 1mm surface mount Molded Chip on Board package, the ALM-1522 balanced amplifier module allows designers to develop smaller or more compact base station products such as pico and femto base station receivers that do not require as much board space as typical discrete solutions.
The ALM-1522 is a fully matched two-stage LNA module with no external RF matching components, which helps designers simplify their design and helps shorten their design to market cycle. Additionally, this balanced LNA module replaces four discrete transistors that are typically found in the traditional TMA, LNA/Filter combiner and LNA products used in base station front end receivers.
Features:
The ALM-1522 features low noise figure 0.6dB, high linearity and OP1dB, 5V supply, adjustable current for optimum NF or OIP3, high gain: 31dB, shutdown function, GaAs E-pHEMT technology, Tape and reel packaging option available, MSL-3, unconditionally stable, Pb-Free and RoHS compliant, Halogen-Free.
