D e s c r i p t i o n
M/A-COM’s MAAM28000-A1 is a wide band, MMIC amplifier
housed in a small 8-lead ceramic package. It includes two distributed gain stages to obtain flat gain and a good, 50-ohm,
input and output impedance match over a very wide
bandwidth. The MAAM28000-A1 operates from a single
+10 V supply. It is fully monolithic, re q u i res no external
components, and is provided in a low-cost, user- f r i e n d l y ,
m i c rowave package.
The MAAM28000-A1 perf o rms well as a generic IF, driver or
b u ffer amplifier where high gain, excellent linearity and low
power consumption are important. Because of its wide bandwidth, the MAAM28000-A1 can be used in numerous comm e rcial and government system applications, such as satellite
communications, RLL, EW and radar.
The MAAM28000-A1 is manufactured in-house using a re l iable, 0.5-micron, GaAs MESFET process. This product is
100% RF tested to ensure compliance to perf o rmance
