Abstract
Stanford Microdevices’ SGA-9289 is a high performance SiGe amplifier designed for operation from DC to 3500 MHz. The amplifier is manufactured using the latest Silicon Germanium Heterostructure Bipolar Transistor (SiGe HBT) process. The process has a VBCEO=8V and an fT=25 GHz. The SiGe HBT process makes the SGA-9289 a very cost-effective solution for applications requiring high linearity at moderate biasing levels. This application note illustrates several application circuits for key frequency bands in the 800-2500 MHz spectrum.
