General Description
GVA-81+ (RoHS compliant) is a wideband amplifier offering high dynamic range. Lead finish is SnAgNi.
It has repeatable performance from lot to lot and is enclosed in a SOT-89 package. It uses patented
Transient Protected Darlington configuration and is fabricated using InGaP HBT technology.

Description
RF input pin. This pin requires the use of an external DC blocking capacitor chosen
for the frequency of operation.
RF output and bias pin. DC voltage is present on this pin; therefore a DC blocking
capacitor is necessary for proper operation. An RF choke is needed to feed DC bias
without loss of RF signal due to the bias connection, as shown in “Recommended
Application Circuit”, Fig. 2
Connections to ground. Use via holes as shown in “Suggested Layout for PCB
Design” to reduce ground path inductance for best performance.
