浩时健电子代理HITTITE全系列放大器产品，供应HM*78ST89:Hittite Microwave公司宣布推出两款新型SiGe HBT增益模块MMIC放大器——HM*78ST89和HM*78MP86。新款器件适用于DC至4GHz蜂窝/3G、FWA、CATV、微波射频和测试设备。

这两种SiGe HBT增益模块可与50Ω负载匹配，能提供22dB增益，可用作各种RF和IF设备的可层叠增益级。HM*78ST89和HM*78MP86在1GHz下的输出P1dB为+18dBm，输出IP3为+32dBm，也可用作LO缓冲放大器或PA预置驱动器。这些多用途MMIC放大器可在+5V到+12V的单电源电压下工作，电流消耗*62mA，且无需任何外部匹配元件。这两款产品均能提供1C级(1000V HBM) *D*护能力，性能更加稳定。

The HM*78ST89(E) is a SiGe Heterojunction Bipolar Transistor (HBT) Gain Block MMIC SMT amplifiers covering DC to 4 GHz. Packaged in an industry standard SOT89, the amplifier can be used as a cascadable 50 Ohm RF/IF gain stage as well as a LO or PA driver with up to +20 dBm output power. The HM*78ST89(E) offers 22 dB of gain with a +33 dBm output IP3 at 850 MHz while requiring only 62mA 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.

Features • P1dB Output Power: +18 dBm • Gain: 22 dB • Output IP3: +33 dBm • Cascadable 50 Ohm I/Os • Single Supply: +5V to +8V • Industry Standard SOT89 Package • Robust 1,000V *D, Cl* 1C • Included in the HMC-DK001 Designer’s Kit

T*ical Applications • Cellular / PCS / 3G • Fixed Wireless & WLAN • CATV, Cable Modem & DBS • Microwave Radio & Test Equipment
