Description

The XP1042-QT is a packaged driver amplifier that

operates over the 12 - 16 GHz frequency band. The

device provides 21 dB gain and 38 dBm Output

Third Order Intercept Point (OIP3) across the band

and is offered in an industry standard, fully molded

3 mm QFN package. The device includes on-chip

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

Class 1A devices.

3. Exceeding any one or combination of these limits may cause

permanent damage to this device.

4. MACOM does not recommend sustained operation near these

survivability limits.

5. Operating at nominal conditions with TJ ≤ +150°C will ensure

MTTF > 1 x 106 hours.

App Note [1] Biasing - As shown in the Pin Designations table, the device is operated by biasing VD1,2,3

at 5 V with 125, 125, 250 mA respectively. It is recommended to use active bias to keep the currents

constant in order to maintain the best performance over temperature. Depending on the supply voltage

available and the power dissipation constraints, the bias circuit may be a single transistor or a low power

operational amplifier, with a low value resistor in series with the drain supply used to sense the current. The

gate of the pHEMT is controlled to maintain correct drain current and thus drain voltage. The typical gate

voltage needed to do this is –1 V. Make sure to sequence the applied voltage to ensure negative gate bias

is available before applying the positive drain supply.

App Note [2] Board Layout - As shown in the board layout, it is recommended to provide 100 pF

decoupling caps as close to the bias pins as possible, with additional 10 μF decoupling caps.
