The HMC478 devices are SiGe, heterojunction bipolar transistor (HBT), gain block MMIC, SMT amplifiers covering dc to 4 GHz. These amplifiers can be used as cascadable 50 Ω RF/IF gain stages as well as LO or PA drivers with up to 17 dBm or 20 dBm output power. These amplifiers offer 22 dB or 23 dB of gain with 31 dBm, 32 dBm, or 33 dBm output IP3 at 850 MHz, while requiring only 62 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 bias components.
Applications
- Cellular/PCS/3G/4G
- Fixed wireless and WLAN
- CATV, cable modem, and direct broadcast satellite (DBS)
- Microwave radio and test equipment
