CMM1331-SM

Features

❏ 32.0 dBm (Typ.) Saturated Output Power
❏ 32.0 dB (Typ.) Linear Gain
❏ Fully Matched
❏ Unconditionally Stable
❏ Low-Cost Surface Mount Package
❏ Optimum Thermal Dissipation

Applications
❏ Ku-Band VSAT Transmit Subsystems

Description

The CMM1331-SM is a four-stage pHEMT GaAs
MMIC power amplifier that is ideally suited for transmit
subsystems designed for Ku-Band VSAT applications. The
CMM1331-SM provides 32.0 dB linear gain and delivers

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 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. 0.1µF 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.
