The HMC281 chip is a three stage GaAs MMIC Low Noise Amplifier (LNA) which covers the frequency range of 18 to 32 GHz. The chip can easily be integrated into Multi-Chip Modules (MCMs) due to its small (1.62 mm2) size. The chip utilizes a GaAs PHEMT process offering 22 dB gain from a bias supply of +3.5V @ 60mA with a noise figure of 2.5 dB. This LNA can be used in millimeterwave point-to-point radios, LMDS, VSAT, and other SATCOM applications. All data is with the chip in a 50 ohm test fixture connected via ribbon bonds of minimal length. The HMC281 may be used in conjunction with HMC143, HMC203, HMC258, HMC264, or HMC265 mixers to realize a microwave or millimeterwave system receiver. |
