RF MEMS
SGA5586Z
DC to 4000MHz, CASCADABLE SiGe HBT
MMIC AMPLIFIER
The SGA5586Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton 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 intermodu-
lation products. Only two DC-blocking capacitors, a bias resistor, and an
optional RF choke are required for operation.

Pin Function Description
1RF IN
RF input pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of operation.
2, 4 GND Connection to ground. For optimum RF performance, use via holes as close to ground leads as possible to reduce lead
inductance.
3RF OUT/BIAS
RF output and bias pin. DC voltage is present on this pin, therefore a DC blocking capacitor is necessary for proper oper-
ation.
