HMC449

The HMC449 die is a x2 active broadband frequency multiplier chip utilizing GaAs PHEMT technology. When drThe HMC462 is a GaAs MMIC PHEMT Low Noise Distributed Amplifi er die which operates between 2 and 20 GHz. The amplifi er provides 15 dB of gain, 2.0 to 2.5 dB noise fi gure and +15 dBm of output power at 1 dB gain compression while requiring only 63 mA from a single +5V supply. Gain fl atness is excellent at ±0.5 dB from 6 - 18 GHz making the HMC462 ideal for EW, ECM and RADAR applications. The HMC462 requires a single supply of +5V @ 63 mA and is the self-biased version of the HMC463. The wideband amplifi er I/Os are internally matched to 50 Ohms facilitating easy integration into Multi-Chip-Modules (MCMs). All data is with the chip in a 50 Ohm test fi xture connected via 0.025mm (1 mil) diameter wire bonds of minimal length 0.31mm (12 mils). iven 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 fi xture connected via 0.076mm x 0.0127mm (3mil x 0.5mil) ribbon bonds of minimal length 0.31mm (<12mils).
