SMA428ATR Datasheet | STMicroelectronics

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 ponents. Applying supply voltage to the GS pin and grounding Vcc pin, it provides a reduced gain step of 35 d B. SMA428A is housed in ultra miniature SOT323-6L package(LEAD FREE), the relative dimensions are 1.15mmx1.8mm with 0.8mm thickness.
