Product Summary
The SGA6589 is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring I 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 80mA, the SGA6589 typically provides +32.5 dBm output IP3, 25.5 dB of gain, and +21.5 dBm of IdB 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. The SGA6589 is ideal for: (1)PA Driver Amplifier; (2)Cellular, PCS, GSM, UMTS; (3)IF Amplifier; (4)Wireless Data, Satellite.
