AM-/AMC-157 High Performance Isolation Amplifier, 12.54 dB Gain 20 - 400 MHz Features • • • • TO-8-1 35 dB Typical Reverse Isolation +42 dBm Typical Third Order Intercept +24 dBm Typical 1 dB Compression 1.2:1 Typical VSWR Description M/A-COM's AM-157 is a high performance isolation amplifier with high intercept and compression points. The use of coupler feedback minimizes current in a high intercept amplifier. This amplifier has been optimized for low VSWR to improve system performance. This amplifier is packaged in a TO-8-1 package, and is also available with SMA connectors. The ground plane on the PC board should be configured to remove heat from under the package. AM-157 is ideally suited for use where a high isolation, high intercept amplifier is required Ordering Information Part Number 1 AM-157 PIN AMC-157 SMA Package TO-8-1 package Connectorized C-32 1. Mounting kit part number AU00071 required for PCB applications. Absolute Maximum Ratings 2 Parameter Absolute Maximum Max.
