General Description
The HMC471MS8G is a SiGe HBT Dual Channel Gain Block MMIC SMT amplifier covering DC to 5 GHz. This versatile product contains two gain blocks, packaged in a single 8 lead plastic MSOP, for use as either separate cascadable 50 Ohm RF/IF gain stages, LO or PA drivers or with both amplifi ers combined utilizing external 90° hybrids to create a high linearity driver amplifi er. Each amplifier in the HMC471MS8G offers 20 dB of gain, +20dBm P1dB with a +34 dBm output IP3 at 850 MHz while requiring only 80 mA from a single positive supply. The combined dual amplifier circuit delivers up to +21 dBm P1dB with +36dBm OIP3 for specific application bands through 4 GHz.
