ADVANCED INFORMATION
The Raytheon RMDA25000 is a high efficiency driver amplifier designed for use in point to point radio, point to
multi-point communications, LMDS and other millimeter wave applications. The RMDA25000 is a 3-stage GaAs
MMIC amplifier utilizing Raytheon’s advanced 0.15µm gate length Power PHEMT process and can be used in
conjunction with other driver or power amplifiers to achieve the required total power output.

CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
Chip carrier material should be selected to have GaAs compatible thermal coefficient of expansion and high thermal
conductivity such as copper molybdenum or copper tungsten. The chip carrier should be machined, finished flat,
plated with gold over nickel and should be capable of withstanding 325°C for 15 minutes.
Die attachment for power devices should utilize Gold/Tin (80/20) eutectic alloy solder and should avoid hydrogen
environment for PHEMT devices. Note that the backside of the chip is gold plated and is used as RF and DC
Ground.
These GaAs devices should be handled with care and stored in dry nitrogen environment to prevent contamination
of bonding surfaces. These are ESD sensitive devices and should be handled with appropriate precaution including
the use of wrist-grounding straps. All die attach and wire/ribbon bond equipment must be well grounded to
prevent static discharges through the device.
Recommended wire bonding uses 3 mils wide and 0.5 mil thick gold ribbon with lengths as short as practical
allowing for appropriate stress relief. The RF input and output bonds should be typically 0.012” long
corresponding to a typically 2 mils gap between the chip and the substrate material.
Note:
1. Typical range of the negative gate voltages is -0.9 to 0.0V to set typical Idq of 250 mA.
Characteristic performance data and specifications are subject to change without notice.
