DESCRIPTION
SMA427A is a product of the SMA Family (Silicon
MMIC Amplifiers). Housed in the ultra miniature
4-lead SC-70 (SOT323-4L LEAD FREE) surface
mount plastic package, it embeds the state of the art
Silicon ST technology. The amplifier application
shows excellent RF performance using only two
external component in the 1000-2000MHz frequency
range.
