HMC481ST89 / 481ST89E v02.0710 AMPLIFIERS - DRIVER & GAIN BLOCK - SMT 8 SiGe HBT GAIN BLOCK MMIC AMPLIFIER, DC - 5 GHz Typical Applications Features The HMC481ST89 / HMC481ST89E is an ideal RF/IF gain block & LO or PA driver for: P1dB Output Power: +19 dBm • Cellular / PCS / 3G Output IP3: +33 dBm • Fixed Wireless & WLAN Cascadable 50 Ohm I/Os • CATV, Cable Modem & DBS Single Supply: +6V to +12V • Microwave Radio & Test Equipment Industry Standard SOT89 Package Gain: 20 dB Included in the HMC-DK001 Designer’s Kits Functional Diagram General Description The HMC481ST89 & HMC481ST89E are SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifiers covering DC to 5 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 +21 dBm output power. The HMC481ST89(E) 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 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.
