Product Description
BeRex’s BG12C is a high performance InGaP/GaAs HBT MMIC amplifier, internally matched to 50 Ohms and uses a patented temperature compensation circuit to provide stable current over the operating temperature range without the need for external components. The BG12C is designed for high linearity gain block applications that require excellent gain flatness. It is packaged in a RoHS-compliant with SOT-89 surface mount package.
