SBA4089Z

DCto5GHz, CASCADABLE InGaP/GaAs HBT

MMIC AMPLIFIER

Package: SOT-89

Product Description

RFMD’s SBA4089Z is a high performance InGaP/GaAs Heterojunction Bipolar Tran-

sistor MMIC Amplifier. A Darlington configuration designed with InGaP process tech-

nology provides broadband performance up to 5GHz with excellent thermal

performance. The heterojunction increases breakdown voltage and minimizes leak-

age current between junctions. Cancellation of emitter junction non-linearities

results in higher suppression of intermodulation products. Only a single positive

supply voltage, DC-blocking capacitors, a bias resistor, and an optional RF choke

are required for operation.

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 under device pins 2 and 4 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.

Description

RF input pin. This pin requires the use of an external DC-blocking capacitor chosen for the frequency of opera-

tion.

Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as

possible.

RF output and bias pin. DC voltage is present on this pin, therefore a DC-blocking capacitor is necessary for

proper operation.
