Product Description Stanford Microdevices SGA-3463 is a high performance SiGe Heterojunction Bipolar Transistor MMIC Amplifier. A Darlington configuration featuring 1 micron emitters provides high FT 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 35mA , the SGA-3463 typically provides +24 dBm output IP3, 22 dB of gain, and +11.3 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. VD= 2.9 V, ID= 35 mA (Typ.)

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. 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. 6 5 4 1 GND A34 Connection to ground. Use via holes for best performance to reduce lead inductance as close to ground leads as possible. 6 Part Identification Marking The part will be marked with an A34 designator on the top surface of the package. RF OUT/ RF output and bias pin. DC voltage is BIAS present on this pin, therefore a DC blocking capacitor is necessary for proper operation. 1 2 3 For package dimensions, refer to outline drawing at www.stanfordmicro.com Caution: ESD sensitive 2,4,5 GND Sames as Pin 2 Part Number Ordering Information Appropriate precautions in handling, packaging and testing devices must be observed. 726 Palomar Ave., Sunnyvale, CA 94085 Description Part Number Reel Size Devices/Reel SGA-3463 7" 3000 Phone: (800) SMI-MMIC 4 http://www.stanfordmicro.com EDS-100636 Rev.
