HMC741 InGaP HBT Active Bias MMIC Amplifier, 0.05 - 3 GHz

Product Details

The HMC741 is an InGaP Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifier covering 0.05 to 3 GHz. Packaged in an industry standard SOT89, the amplifier can be used as a cascadable 50 Ohm RF or IF gain stage as well as a PA or LO driver with up to +18.5 dBm output power. The HMC741 offers 20 dB of gain with a +42 dBm output IP3 at 200 MHz, and can operate directly from a +5V supply. The HMC741 exhibits excellent gain and output power stability over temperature, while requiring a minimal number of external bias components.
