RMWM26001
26 GHz Mixer MMIC
PRODUCT INFORMATION
Description The RMWM26001 is a 26 GHz Mixer designed to be used in point to point radios, point to multi-point
communications, LMDS, and other millimeter wave applications. In conjunction with other Raytheon amplifiers,
multipliers and mixers it forms part of a complete 23 and 26 GHz transmit/receive chipset. The RMWM26001 is a
GaAs MMIC diode mixer utilizing Raytheon’s 0.25µm power PHEMT process. The MMIC can be used as both an
Upconverter and a Downconverter and is sufficiently versatile to serve in a variety of mixer applications.

Application CAUTION: THIS IS AN ESD SENSITIVE DEVICE.
Information
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 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 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 mil between the chip and the substrate material.
Note:
1. Device 100% RF tested as downconverter only. LO drive = +12 dBm, RF Pin = -10 dBm, IF = 2.6 GHz.
Characteristic performance data and specifications are subject to change without notice.
