Product Description
Features
RFMD’s CGA-3318Z is a high performance Silicon Germanium HBT MMIC Amplifier.
Designed with SiGe process technology for excellent linearity at an exceptional
price. A Darlington configuration is utilized for broadband performance. The heterojunction increases breakdown voltage and minimizes leakage current between
junctions. The CGA-3318Z contains two amplifiers for use in wideband Push-Pull
CATV amplifiers requiring excellent second order performance. The second and
third order non-linearities are greatly improved in the push-pull configuration.

Description
Device 1. RF input pin. This pin requires the use of an external DC-blocking capacitor as shown in the schematic.
Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as
possible.
Device 2. RF input pin. This pin requires the use of an external DC-blocking capacitor as shown in the schematic.
Device 2. RF output and bias pin. Bias should be supplied to this pin through an external series resistor and RF
choke inductor. Because DC biasing is present on this pin, a DC-blocking capacitor should be used in most applications. The supply side of the bias network should be well bypassed.
Same as pins 2 and 3.
Device 1. Same as pin 5.
Exposed area on the bottom side of the package must be soldered to the ground plane of the board for optimum
thermal and RF performance. Several vias should be located under the EPAD as shown in the recommended
land pattern.
