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).
