HMC481ST89/HMC481ST89E CATV Amplifier Evaluation Board

HMC481ST89 Evaluation PCB, EB/PCB

The HMC481 devices are SiGe or InGaP, heterojunction bipolar transistor (HBT), gain block MMIC SMT amplifiers covering dc to 5 GHz. Available in Micro-P and SOT89 packaging, the amplifiers can be used as cascadable 50 Ω RF/IF gain stages as well as LO or PA drivers with up to 21 dBm output power. The HMC481 devices offer 20 dB of gain with a 33 dBm output IP3 at 1 GHz, while requiring only 79 mA from a single positive supply. The Darlington feedback topology results in reduced sensitivity to normal process variations and excellent gain stability over temperature, while requiring a minimal number of external components.
