| HMC474SC70 / 474SC70E v00.0607 SiGe HBT GAIN BLOCK MMIC AMPLIFIER, DC - 6 GHz 5 DRIVER & GAIN BLOCK AMPLIFIERS - SMT Typical Applications The HMC474SC70(E) is an ideal for: * Cellular / PCS / 3G * WiBro / WiMAX / 4G * Fixed Wireless & WLAN * CATV, Cable Modem & DBS * Microwave Radio & Test Equipment Features Gain: 15 dB P1dB Output Power: +8 dBm Output IP3: +20 dBm Cascadable 50 Ohm I/Os Single Supply: +3V to +10V Industry Standard SC70 Package Functional Diagram General Description The HMC474SC70(E) is a general purpose SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier covering DC to 6 GHz. This industry standard SC70 packaged amplifier can be used as a cascadable 50 Ohm RF/IF gain stage with up to +8 dBm output power. The HMC474SC70(E) offers 15 dB of gain with a +20 dBm output IP3 at 850 MHz while requiring only 25 mA from a single positive supply as low as +3V. 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.

HMC474SC70(E) 117360 Evaluation PCB [1] The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads 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.
