HMC478ST89 / 478ST89E v05.0710 AMPLIFIERS - DRIVER & GAIN BLOCK - SMT 8 SiGe HBT GAIN BLOCK MMIC AMPLIFIER, DC - 4 GHz Typical Applications Features The HMC478ST89 / HMC478ST89E is an ideal RF/IF gain block & LO or PA driver: P1dB Output Power: +18 dBm • Cellular / PCS / 3G Output IP3: +30 dBm • Fixed Wireless & WLAN Cascadable 50 Ohm I/Os • CATV, Cable Modem & DBS Single Supply: +5V to +8V • Microwave Radio & Test Equipment Industry Standard SOT89 Package Gain: 22 dB Robust 1,000V ESD, Class 1C Included in the HMC-DK001 Designer’s Kit General Description Functional Diagram The HMC478ST89 & HMC478ST89E are SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifiers covering DC to 4 GHz. Packaged in an industry standard SOT89, the amplifier can be used as a cascadable 50 Ohm RF/IF gain stage as well as a LO or PA driver with up to +20 dBm output power. The HMC478ST89(E) offers 22 dB of gain with a +30 dBm output IP3 at 850 MHz while requiring only 62mA from a single positive supply. The Darlington feedback pair used results in reduced sensitivity to normal process variations and excellent gain stability over temperature while requiring a minimal number of external bias components.
