AM-/AMC-142 Low Noise Amplifier, 12 dB Gain, 200 - 1000 MHz Features n n n V 3.00 TO-8-1 2.2 dB Typical Midband Noise Figure +6 dBm Typical Midband Output Power +20 dBm Typical Midband Third Order Intercept Description M/A-COM’s AM-142 is a coupler feedback amplifier with low noise figure and high intercept points for the low bias current. The use of coupler feedback minimizes noise figure 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-142 are ideally suited for use where a low noise, high reliability amplifier is required. C-32 Absolute Maximum Ratings 1 Parameter Absolute Maximum Max. Input Power +20 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.
