DCto5GHz, CASCADABLE InGaP/GaAs HBT
MMIC AMPLIFIER
Package: SOT-89
Product Description
Features
RFMD’s SBA-4089 is a high performance InGaP/GaAs Heterojunction Bipolar Transistor MMIC Amplifier. A Darlington configuration designed with InGaP process technology provides broadband performance up to 5GHz with 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 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 operation.
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.
