InGaP HBT Gain Block Amplifier Chip, DC - 4 GHz

The HMC395 die is a GaAs InGaP Heterojunction Bi-polar Transistor (HBT) Gain Block MMIC DC - 4 GHz amplifier. This amplifier die can be used as either a cascadable 50 Ohm gain stage or to drive the LO of HMC mixers with up to +17dBm output power. The HMC395 offers 16 dB of gain and an output IP3 of +31dBm while requiring only 54mA from a +5V supply.

The Darlington feedback pair used results in reduced sensitivity to normal process variations and yields excellent gain stability over temperature while requiring a minimal number of external bias components. The HMC395 can easily be integrated into Multi-Chip-Modules (MCMs) due to its small (0.22mm²) size. All data is with the chip in a 50 Ohm test fixture connected via 0.025mm (1mil) diameter wire bonds of minimal length 0.5mm (20mils).
