CGA-3318Z CGA-3318Z Dual CATV Broadband High Linearity SiGe HBT Amplifier DUAL CATV BROADBAND HIGH LINEARITY SiGe HBT AMPLIFIER Package: ESOP-8 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.

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.
