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.

processing as these by-products are dangerous to the human body if inhaled, ingested, or swallowed.
Observe government laws and company regulations when discarding this product. This product must be
discarded in accordance with methods specified by applicable hazardous waste procedures.
Life Support Policy
- Mimix Broadband's products are not authorized for use as critical components in life support
devices or systems without the express written approval of the President and General Counsel of Mimix Broadband. As
used herein: (1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into
the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions
for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. (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.
Mimix Lead-Free RoHS Compliant Program -
Mimix has an active program in place to meet customer and governmental
requirements for eliminating lead (Pb) and other environmentally hazardous materials from our products. All Mimix
RoHS compliant components are form, fit and functional replacements for their non-RoHS equivalents. Lead plating of
our RoHS compliant parts is 100% matte tin (Sn) over copper alloy and is backwards compatible with current standard
SnPb low-temperature reflow processes as well as higher temperature (260°C reflow) “Pb Free” processes.
