Product Description
The SGA0163Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one-micron emitters provides high F
T
and
excellent thermal perfomance. 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.

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

Notes:
1. Provide a large ground pad area under device
pins 1, 2, 4, & 5 with many plated via holes as
shown.
2. Dimensions given for 50 Ohm RF I/O lines are for
31 mil thick Getek. Scale accordingly for different
board thicknesses and dielectric contants.
3. We recommend 1 or 2 ounce copper. Measure-
ments for this data sheet were made on a 31 mil
thick Getek with 1 ounce copper on both sides.
