13.50-14.50 GHz 2.5-Watt Power Amplifier
August 2007 - Rev 16-Aug-07
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
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 13.5 to 14.5 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.

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.

(2) A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. Package Attachment - This packaged product from Mimix Broadband is provided as a rugged surface mount package
compatible with high volume solder installation. Care should be taken not to apply heavy pressure to the top or base material to avoid package damage. Vacuum tools or other suitable pick and place equipment may be used to pick and place this part. Care should be taken to ensure that there are no voids or gaps in the solder connection so that good RF, DC and ground connections are maintained. Voids or gaps can eventually lead not only to RF performance degradation, but reduced reliability and life of the product due to thermal stress.
