RMDA1840
18-40 GHz Broad Band Driver Amplifier
MMIC
PRODUCT INFORMATION
Description
The RMDA1840 is a 4-stage GaAs MMIC amplifier designed as a 18 to 40 GHz broad band amplifier for use in point
to point radios, point to multi-point communications, LMDS, and other millimeter wave applications. The
RMDA1840 utilizes Raytheon鈥檚 0.25碌m power PHEMT process and is sufficiently versatile to serve in a variety of
applications, such as a driver amplifier or a frequency multiplier.
