General Description
The HMC449 die is a x2 active broadband
frequency multiplier chip utilizing GaAs PHEMT
technology. When driven by a 0 dBm signal the
multiplier provides +10 dBm typical output power
from 28 to 32 GHz. The Fo and 3Fo isolations
are >34 dBc and >17 dBc respectively at 30 GHz.
The HMC449 is ideal for use in LO multiplier
chains yielding a reduced parts count vs. traditional
approaches. The low additive SSB Phase Noise of
-132 dBc/Hz at 100 kHz offset helps maintain good
system noise performance. All data is with the chip
in a 50 ohm test fixture connected via 0.076mm x
0.0127mm (3mil x 0.5mil) ribbon bonds of minimal
length 0.31mm (<12mils).
