HMC481MP86

The HMC481MP86 is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifi er covering DC to 5 GHz. This Micro-P packaged amplifi er can be used as a cascadable 50 Ohm RF/IF gain stage as well as a LO or PA driver with up to +21 dBm output power. The HMC481MP86 offers 20 dB of gain with a +33 dBm output IP3 at 850 MHz while requiring only 74 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.
