Hittite Microwave Corporation introduces a high linearity InGaP HBT Gain Block MMIC Amplifier which is suitable for IF and RF applications from DC to 4.5 GHz, including Cellular/PCS/3G, Broadband, WiBro and WiMAX. The HMC475ST89(E) is an InGaP HBT Gain Block MMIC Amplifier which operates from DC to 4.5 GHz, and features high output P1dB of +22 dBm, high output IP3 of +35 dBm, and up to 22 dB of small signal gain. The HMC475ST89(E) is fully matched to 50 Ohms, and is suitable as a cascadeable gain stage in IF, RF, and PA pre-driver amplifier applications in Cellular/PCS/3G, Broadband, Wibro and WiMAX systems. This versatile gain block amplifier is housed in an industry standard and RoHS compliant SOT89 "E" SMT package, and shares a common pinout within Hittite's broad line of SiGe and InGaP HBT gain block amplifiers. The HMC475ST89(E) operates from single +8V supply and consumes only 110 mA of current.
