Low Noise Amplifier, 100 - 600 MHz AM-191 V3.00 Features n n n FP-3 2.5 dB Typical Midband Noise Figure +23 dBm Typical 1 dB Compression Point +32 dBm Typical Third Order Intercept Description M/A-COM’s AM-191 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. Due to the internal power dissipation the thermal rise minimized. The ground plane on the PC board should be configured to remove heat from under the package. AM-191 is ideally suited for use where a low noise, high reliability amplifier is required. Absolute Maximum Ratings 1 Parameter Absolute Maximum Max. Input Power +10 dBm Vbias +15.75 V Operating Temperature -55°C to +85°C Storage Temperature -65°C to +125°C 1. Operation of this device above any one of these parameters may cause permanent damage.

All specifications apply when operated at +15 VDC, with 50 ohms source and load impedance. 3. Heat Sinking: Operation at case temperature above 95°C is not recommended. Heat sinking adequate to dissipate 1.25 W must be provided in use.
