Description
4 mil substrate
Conversion loss 14.5 dB (typ.)
No DC bias required
Chip size 1.6 mm x 1.05 mm
Features
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 proc ess and is sufficiently versatile to serve in a variety of multiplier
applications.

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.

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.
