SMA428ATR

SMA428A High Gain, Low Noise Amplifier PRELIMINARY DATA HIGH GAIN Gp = 21 dB at 1.85 GHz LOW NOISE FIGURE NF = 1.3 dB at 1.85 GHz LOW CURRENT CONSUMPTION 5.9 mA OPEN COLLECTOR OUTPUT TYPICAL SUPPLY VOLTAGE: 2.4-3 V GAIN-STEP-MODE (36dB) ULTRA MINIATURE SOT323-6L PACKAGE (LEAD FREE) APPLICATIONS LNA FOR CELLULAR MARKET (ideal for GSM900, DCS1800 and PCS1900). LNA FOR GPS APPLICATIONS DESCRIPTION High gain and low noise figures make the SMA428A an ideal solution for Low Noise Amplifiers and receiver front end stages up to 2.5 GHz. SMA428A’s typical supply voltage range is 2.4 to 3.3 volts. It shows excellent performances in terms of NF, Gain and current consumption, using just 3 external matching components. Applying supply voltage to the GS pin and grounding Vcc pin, it provides a reduced gain step of 35 dB. SMA428A is housed in ultra miniature SOT323-6L package(LEAD FREE), the relative dimensions are 1.15mmx1.8mm with 0.8mm thickness.
