AM-/AMC-138 High Performance Amplifier, 25 dB Gain, 10 - 200 MHz Features n n n V 5.00 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 internal power dissipation the thermal rise should be 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. C-25 Absolute Maximum Ratings 1 Parameter Absolute Maximum Max. Input Power +15 dBm Vbias +17.0 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 damange. Pin Configuration Pin # Function Pin # Function 1 RF OUT 6 RF IN 2 GND 7 GND 3 GND 8 GND 4 GND 9 GND 10 Vbias2 5 Vbias 2 2. Bias may be applied to either a single bias pin, or both bias pins. 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.

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 3.5W must be provided in use. The flange should be screwed down to the heat sink, which should be RF ground.
