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 are 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.

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).
10. 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

chip resistor (as shown in
the Recommended PCB Configuration).
