SMA540B Active Biased RF Transistor PRELIMINARY DATA • HIGH GAIN LOW NOISE AMPLIFIERS Gms = 19 dB at 1.8 GHz • CURRENT EASY ADJUSTABLE BY AN EXTERNAL RESISTOR • OPEN COLLECTOR OUTPUT • TYPICAL SUPPLY VOLTAGE: 1.4-3.3 V • TRANSITION FREQUENCY 42 GHz • ULTRA MINIATURE SOT323-4L PACKAGE (LEAD FREE) APPLICATIONS • WIDEBAND APPLICATIONS • CELLULAR AND CORDLESS TELEPHONES • HIGH FREQUENCY OSCILLATORS Bias Bias, 4 C, 3 SOT323-4L (SC70) ORDER CODE SMA540BTR BRANDING TBD DESCRIPTION The SMA540B is a NPN Transistor integrating a current mirror as biasing. In this way the IC (collector current) can be controlled setting the current at Bias pin according to IC = 10 * IBIAS. The IBIAS current is easy adjustable using an external resistor.
