| HMC475ST89 / 475ST89E v01.0107 InGaP HBT GAIN BLOCK MMIC AMPLIFIER, DC - 4.5 GHz 5 AMPLIFIERS - SMT Typical Applications The HMC475ST89 / HMC475ST89E 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 * IF and RF Applications Features P1dB Output Power: +22 dBm Gain: 21.5 dB Output IP3: +35 dBm Cascadable 50 Ohm I/Os Single Supply: +8V to +12V Industry Standard SOT89 Package Functional Diagram General Description The HMC475ST89(E) is a InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier covering DC to 4.5 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 +25 dBm output power. The HMC475ST89(E) offers 21.5 dB of gain and +35 dBm output IP3 at 850 MHz while requiring only 110 mA from a single positive supply. The Darlington topology 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.
