SGA-4463 Product Description DC-3500 MHz, Cascadable SiGe HBT MMIC Amplifier Sirenza Microdevices SGA-4463 is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring 1 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 intermodulation products. At 850 Mhz and 45mA , the SGA4463 typically provides +27 dBm output IP3, 19 dB of gain, and +14 dBm of 1dB compressed power using a single positive voltage supply. Only 2 DC-blocking capacitors, a bias resistor and an optional RF choke are required for operation.

Use a large ground pad area near device pins 1, 2, 4, and 5 with many plated through-holes as shown. CB 2. We recommend 1 or 2 ounce copper. Measurements for this data sheet were made on a 31 mil thick FR-4 board with 1 ounce copper on both sides. Part Identification Marking The part will be marked with an A44 designator on the top surface of the package. Pin # Function 3 RF IN RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. GND Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible. 6 5 4 1, 2, 4, 5 A44 1 2 3 RF output and bias pin. DC voltage is RF OUT/ present on this pin, therefore a DC BIAS blocking capacitor is necessary for proper operation. 6 Part Number Ordering Information Caution: ESD sensitive Appropriate precautions in handling, packaging and testing devices must be observed. 522 Almanor Ave., Sunnyvale, CA 94085 Description Part Number Reel Size Devices/Reel SGA-4463 7" 3000 Phone: (800) SMI-MMIC 4 http://www.sirenza.com EDS-100644 Rev.
