GVA-81-DG+ (RoHS compliant) is a wideband high gain amplifier die offering high dynamic range. It uses patented Transient Protected Darlington configuration and is fabricated using InGaP HBT technology, offering flat gain over a broad frequency range and high IP3. It provides good input and output return loss over a broad frequency range without the need for external matching components. Provided as an unpackaged amplifier die on GaAs, this model allows easy integration directly into the user’s hybrids.
