ZAMP002
800-2500MHz MMIC WIDEBAND AMPLIFIER
Medium Power, 22dB Gain, Wide Dynamic Range
DESCRIPTION
The ZAMP002 is an low current high performance RF
amplifier designed for L band and IF applications.
Although the ZAMP002 has been designed primarily
for DBS applications the ZAMP002 is capable of
extending to frequencies of 2.5GHz so it has a good fit
with various applications. An additional benefit of the
ZAMP002 is it’s rising gain characteristic, this has been
designed to counteract the gain losses found at the
higher frequencies. The ZAMP002 has been optimized
to an input impedance of 50ohms while the output
impedance has been designed for optimum match to
an impedance of 75ohms. Packaged in a small SC70-6
w i t h t he mi ni m um n um be r of e x t e rn a l b ia s
components required it is the ideal solution for space
and current limited applications.
