Product Description
Features
The SGA5486Z is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring one-micron emitters provides high FT 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 intermodulation 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, therefore a DC blocking capacitor is necessary for proper operation.
