DC to 2500MHz, CASCADABLE SiGe HBT
MMIC AMPLIFIER
Package: SOT-363
Product Description
Features
The SGA4563Z 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.

RF OUT/BIAS
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, therefor a DC-blocking capacitor is necessary for proper operation.

31 mil thick Getek. Scale accordingly for different
board thicknesses and dielectric contants.
3. We recommend 1 or 2 ounce copper. Measurements for this data sheet were made on a 31 mil
thick Getek with 1 ounce copper on both sides.
