MICROWAVE CORPORATION v00.0204 HMC479ST89 SiGe HBT GAIN BLOCK MMIC AMPLIFIER, DC - 5.0 GHz Features P1dB Output Power: +18 dBm Gain: 15 dB Output IP3: +33 dBm Cascadable 50 Ohm I/Os Single Supply: +5V to +12V Industry Standard SOT89 Package 8 AMPLIFIERS - SMT Typical Applications The HMC479ST89 is an ideal RF/IF gain block & LO or PA driver: • Cellular / PCS / 3G • Fixed Wireless & WLAN • CATV, Cable Modem & DBS • Microwave Radio & Test Equipment Functional Diagram General Description The HMC479ST89 is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier 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 +20 dBm output power. The HMC479ST89 offers 15 dB of gain with a +33 dBm output IP3 at 850 MHz while requiring only 75 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. ** Circuit Board Material: Rogers 4350 * Reference this number when ordering complete evaluation PCB.
