May 2006 - Rev 24-May-06
CMM1631-SM Features
32dBm (Typ.) Saturated output power 26dB (Typ) Linear Gain Fully Matched Unconditionally Stable Low Cost, Surface Mount Package 6mmX6mmX1.6mm Optimum Thermal Dissipation 7V, 770mA Military Ku Band VSAT Point to Point Radio Ku-Band Space
Applications
General Description
The CMM1631-SM is a four stage pHEMT GaAs MMIC power amplifier packaged in a 6mm X6mm surface mount package. The CMM1631-SM provides 26dB of linear gain and delivers 1.5 watts of output power at saturation operating between 16 to 18GHz. The unconditional stability and internal matching provides for a reduction in external components making this product a simple and low cost solution. The true surface mount package makes it ideal solution in all manufacturing environments. The power amplifier is intended for use in the extended Ku-Band satellite applications.

Note: Due to the high gain of this device it is highly recommended to maintain the reverse isolation (S12) above 50 dB. Biasing Notes 1. Dual bias is required 2. 0.1 F bypass capacitors are needed on PC board as close as possible to pins 1, 5, 6 and 10. 3. Positive (+) bias can be applied either at pin 1 or pin 6. 4. Negative (-) bias can be applied either at pin 5 or pin 6. 5. No DC block is required at RF IN/OUT. 6. Negative (-) bias must be applied before applying positive (+) bias.
