Product Description
Typical Performance1
BeRex’s BGS4 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 BGS4 is designed for high linearity gain block applications that require excellent gain flatness. It is packaged in a RoHS-compliant with SOT-363 surface mount package.
