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.
