RMWT11001
11-33 GHz Tripler MMIC
PRODUCT INFORMATION
Description
The RMWT11001 is an 11 to 33 GHz Tripler designed to be used in the LO chain of 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 38 GHz transmit/receive chipset. The RMWT11001 utilizes Raytheon's 0.25 µm power PHEMT process and is sufficiently versatile to serve in a variety of multiplier applications.

Application Information
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 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.

Recommended Procedure
for Operation
The following sequence must be followed to properly test the amplifier. Step 1: The RMWT11001 does not require DC bias. Apply RF input signal at the appropriate frequency band and input drive level. Step 2: Follow turn-off sequence of: Turn off RF input power.
