Stanford Microdevices' SGA-5486 is a high performance cascadeable 50-ohm amplifier designed for operation at voltages as low as 3.5V. This RFIC uses the latest SiliconGermanium Heterostructure Bipolar Transistor (SiGe HBT) process featuring 1 micron emitters with FT up to 65 GHz.
This circuit uses a darlington pair topology with resistive feedback for broadband performance as well as stability over its entire temperature range. Internally matched to 50 ohm impedance, the SGA-5486 requires only DC blocking and bypass capacitors for external components.
SGA-5486 Features
• DC-2400 MHz Operation • Single Voltage Supply • High Output Intercept: +32.0dBm typ. at 850 MHz • Low Current Draw: 60mA at 3.5V typ. • Low Noise Figure: 3.0dB typ. at 850 MHz
SGA-5486 Typical Application
• Oscillator Amplifiers • PA for Low Power Applications • IF/ RF Buffer Amplifier • Drivers for CATV Amplifiers
