CMM1434-SM

13.50-14.50 GHz 2.5-Watt Power Amplifier March 2006 - Rev 02-Mar-06 CMM1434-SM Features 34.5 dBm (Typ.) Saturated Output Power 31.0 dB (Typ.) Linear Gain Fully Matched Uncondtionally Stable Low-Cost, Surface Mount Package Optimum Thermal Dissipation Applications Ku-Band VSAT Transmit Subsystems General Description The CMM1434-SM is a four-stage pHEMT GaAs MMIC power amplifier that is ideally suited for transmit subsystems designed for Ku-Band VSAT applications. The CMM1434-SM provides 31.0 dB linear gain and delivers 2.5 watts of output power at saturation operating from 13.50 to 14.50 GHz frequency. The unconditional stability and internal matching provides for reduction of external components making this product a simple and low-cost solution. The low-cost 6mm x 6mm x 1.6mm surface mount package offers the same excellent RF and thermal properties as a typical flange package.

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.
