Description
in
ar
y
The PA2100 is a Dual-Band Power Amplifier (PA) Multi-Chip Module (MCM) for use as
a final RF amplifier in GSM900 and DCS1800 hand-held digital cellular equipment and
other applications in the 880-to-915MHz and 1710-to-1785MHz bands. The device consists of a PAIC manufactured on an advanced Gallium Arsenide (GaAs) Heterojunction
Bipolar Transistor (HBT) process, a CMOS current buffer, and off-chip passive components for 50ohm input/output impedance match. The IC chip has two separate blocks, one
of which operates in the GSM900 band and the other in the DCS1800 band. The CMOS
current buffer minimizes the requisite power control current to as low as 60µA. The die and
components are mounted on a laminate substrate and encapsulated with plastic molding to
minimize board space.
Features
