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.

Recommended Application Circuit
Note: This schematic represents the topology of the application circuit
recommended by Celeritek.
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.
Ordering Information
The CMM1434-SM is available in available in tube or tape and reel.
