SiGe HBT GAIN BLOCK MMIC AMPLIFIER, DC - 6 GHz
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
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.
