Description

M/A-COM’s MAALSS0044 is a high performance GaAs MMIC low noise amplifier in a lead-free SOIC-8 surface mount package. The MAALSS0044 employs a fully monolithic design which eliminates the need for external tuning networks. It can be biased using 3- or 5-volt supplies and has an option for biasing at higher currents for increased dynamic range. The MAALSS0044 is ideally suited for use where low noise figure, high gain, high dynamic range and low power consumption ar e required. Typical applications include receiver front ends in the Global Positioning System (GPS) and Japanese Personal Digital Cellular (PDC-1500) markets, as well as standard gain blocks, buffer amps, driver amps and IF amps in both fixed and portable systems. M/A-COM’s MAALSS0044 is fabricated using a mature 0.5-micron gate length GaAs process. The process features full passivation for increased performance reliability.

Pins 1, 4, 5 and 8 must be RF and DC grounded as shown. 7. Pin 3 is the RF input; pin 6 is the RF output. V DD is applied on pin 7. This pin must be bypassed with a 500 pF surface mount MLC capacitor, mounted as close as possible to pin 7, and RF decoupled with a chip inductor having a minimum value of 15 nH (as shown in the Recommended PCB Configuration). 8. Pin 2 allows use of an external resistor to ground for optional, higher current bias. For nominal current operation no resistor is used. For optional 20-mA current operation, connect a 35- to 40-ohm chip resistor (as shown in the Recommended PCB Configuration).
