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

Signal lines should have 50 Ohm impedance while the package ground leads and package bottom should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation board should be mounted to an appropriate heat sink. The evaluation circuit board shown is available from Hittite upon request.
