PRELIMINARY THM2004J Wideband Linear Amplifier SiGe HBT MMIC Wideband Linear Amplifier Descriptions THM2004J is a high performance cascadeable 50-ohm amplifier. This RFIC uses the latest Silicon Germanium Hetero Junction Bipolar Transistor (TAHB09) process of Tachyonics Co., which has 30GHz fT(Normal). THM2004J uses a multi feedback cascade amplifier topology with resistive feedback for broad band performance as well as stability over its entire temperature range. THM2004J also has internally matched 50 ohm impedance and wide bandwidth. Features - Wide band operation : f3dB = 2.2GHz - Single Voltage Supply - Internally Matched to 50 Ohm Input & Output - High Power Gain : 25dB at 1000MHz - Saturated Output Power : Po(sat) = +12dBm at 1000MHz Applications - DBS, LNB , Medium Output - Transmission Stage Buffer (Mobile Communication) SOT363 - IF/RF Buffer Amplifier Function Block Diagram Vcc C L 50Ω IN C 6 1 4 C 50Ω Amp OUT 2,3,5 GND 60-8, Gasan-dong, Kumchun-Gu, Seoul, Korea. 153-023 May. 2004.
