Description
The CMM1331-KU is a four-stage pHEMT GaAs
MMIC power amplifier that is ideally suited for transmit
subsystems designed for Ku-Band VSAT applications. The
CMM1331-KU provides 32.0 dB linear gain and delivers
www.DataSheet4U.com
1.5 watts of output power at saturation operating from
12.70 to 13.50 GHz frequency.
The unconditional stability and internal matching
provides for reduction of external components making this
product a simple and low-cost solution. The package is
designed with a base material of gold-plated copper/molybde-
num composite that offers excellent thermal properties and
minimum mechanical stress.

Biasing Notes
1. Dual bias is required
2. 0.1µF 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.
Mounting Recommendations
1. Leads should be as short as possible.
2. Solder all leads on PC board. Solder area should be as small as possible.
Grounds should be provided for pins 2, 4, 7, and 9 on PC boards.
3. Flange should be screwed down on adequate heat sink. Do not over torque
screws in order to avoid breaks in ceramic and die (tightening torque: 6lbf-in).
4. Grounding shims should be placed between the flange and heat sink to ensure
optimal ground contact. Aluminum or Copper foil can be used.
5. 50RF IN/OUT interface are required for optimal electrical performance.
6. Due to the high gain of this device it is highly recommended to maintain the
reverse isolation (S12) above 50 dB.
