SGA5489Z

DC to 4000MHz, CASCADABLE SiGe HBT

MMIC AMPLIFIER

The SGA5489Z is a high performance SiGe HBT MMIC Amplifier. A Darlington con-

figuration featuring one-micron emitters provides high FT and excellent thermal per-

formance. 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.

Application Schematic

Evaluation Board Layout

Mounting Instructions:

1. Solder the copper pad on the backside of the device package to the ground plane.

2. Use a large ground pad area with many plated through-holes as shown.

3. We recommend 1 or 2 ounce copper. Measurements for this data sheet were made on a 31mil thick FR-4 board with 1

ounce copper on both sides.

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.
