The HMC580ST89E is an InGaP heterojunction bipolar transistor (HBT) Gain Block MMIC Amplifier which operates between DC to 1GHz. The amplifier can be used as a cascadable 50R RF or IF gain stage as well as a PA or LO driver with up to +26dBm output power. The HMC580ST89(E) offers 22dB of gain with a +37dBm output IP3 at 250MHz and can operate directly from a +5V supply. The HMC580ST89(E) exhibits excellent gain and output power stability over temperature, while requiring a minimal number of external bias components.
