Description
M/A-COM’s AM-143 is a coupler feedback amplifier with
low noise figure and high intercept points for the low bias
current. The use of coup ler feedback minimizes no ise fi gure
and current in a high intercept amplifier. This amplifier is
packaged in a TO-8 package. The ground plane on the PC
board should be configured to remove heat from under the
package. AM-143 are ideally suited for use where a low
noise, high reliability amplifier is required.
