| PRELIMINARY Wideband Linear Amplifier THM2003J SiGe HBT MMIC Wideband Linear Amplifier Descriptions THM2003J 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). THM2003J uses a multi feedback cascade amplifier topology with resistive feedback for broad band performance as well as stability over its entire temperature range. THM2003J 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 : 21dB at 1000MHz - Saturated Output Power : Po(sat) = +2dBm at 1000MHz Applications - DBS, LNB , Medium Output - Transmission Stage Buffer (Mobile Communication) - IF/RF Buffer Amplifier Function Block Diagram Vcc C 6 1 SOT363 50U IN C Amp 4 C 50U OUT 2,3,5 GND 60-8, Gasan-dong, Kumchun-Gu, Seoul, Korea. 153-023 May. 2004.
