AM-/AMC-138 High Performance Amplifier, 25 dB Gain 10 - 200 MHz Features • • • FP-9 +49 dBm Typical Midband Third Order Intercept +25 dBm Typical Midband 1 dB Compression 5.3 dB Typical Midband Noise Figure Description M/A-COM’s AM-138 is a coupler feedback amplifier with high intercept and compression points. The use of coupler feedback minimizes noise figure and current in a high intercept amplifier. This amplifier is packaged in a flatpack with flanges. Due to the metal flatpack the thermal rise minimized. The ground plane on the PC board should be configured to remove heat from under the package. AM-138 is ideally suited for use where a high intercept, high reliability amplifier is required.

If bias is applied to both bias pins, it is important that potential ground loops be avoided, and that there is adequate filtering on the bias lines. Specifications subject to change without notice.

All specifications apply when operated at +15 VDC, with 50 ohms source and load impedance. 4. Heat Sinking: Operation at case temperature above 95°C is not recommended. Heat sinking adequate to dissipate 2.7W must be provided in use. The flange should be screwed down to the heat sink, which should be RF ground.
