MMIC AMPLIFIER
Product Description
The SGA3386Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one-micron emitters provides high F
T
and
excellent thermal performance. The heterojunction increases breakdown
voltage and minimizes leakage current between junctions. Cancellation of
emitter junction non-linearities results in higher suppression of intermodu-
lation products. Only two DC-blocking capacitors, a bias resistor, and an
optional RF choke are required for operation.

Description
RF input pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of operation.
Connection to ground. For optimum RF performance, use via holes as close to ground leads as possible to reduce lead
inductance.
RF output and bias pin. DC voltage is present on this pin, therefor a DC-blocking capacitor is necessary for proper opera-
tion.
