Description
The XP1039-QJ is a packaged linear power amplifier that operates from 5.6-7.1 GHz. The device provides 17 dB gain and 48 dBm Output Third Order Intercept Point (OIP3). The packaged amplifier comes in an industry standard, fully molded 6 mm QFN package and is comprised of a two stage power amplifier with an integrated, temperature compensated on-chip power detector. The device includes on-chip ESD protection structures and DC by-pass capacitors to eas e the implementation and volume assembly of the packaged part. The device is specifically designed for use in 6 GHz Point-to-Point radio applications. External DC blocks are requi red. See the reliability note on page 3 for more information.

- North America Tel: 800.366.2266 / Fax: 978.366.2266 Important Reliability Information: The input and output capacitors on the die may be damaged through handling and assembly processes. External DC blocks are recommended on the RF input and output li nes on the PC board. If the output capacitor shorts due to ESD damage, the part will continue to function with slightly degraded performance. IP3 may decrease by approximately 1.5 dB. If the input c apacitor shorts due to ESD damage, the part will continue to function with a slight shift in input return loss. On ce shorted, the capacitor should remain shorted for the standard product lifetime. The external DC blocks are needed to maintain the bias point on the part. Even though the ESD rating using the Human Body Model is Class 1A, it is recommended to treat this part as a Class 0 part. The rate of shorted capacitors due to ESD damage can be in the range of 10%. Shorted capacitors on this part are not subject to the warranty because the part continues to operate reliably with only slightly reduced performance. Recommended Layout MATERIAL: RO4350B, 10 mil. CAPACITORS: 1µF (0805), 1000 pF (0402)

- North America Tel: 800.366.2266 / Fax: 978.366.2266 App Note [1] Biasing - As shown in the Pin Designations table, the device is operated by biasing Vd1,2 at 7.0V. The nominal drain currents are Id1=450mA and Id2=900mA. This ratio of 1:2 between the first and second stage drain currents should be maintained for best linearit y. The typical gate voltages needed are -0.9V. The negative gate voltage must be applied prior to applying the positive drain voltage. The XP1039-QJ is recommended for linear applications only. Active bias is recommended to keep the currents known and constant, and to maintain the best performanc e over temperature. Depending on the supply voltage available and the power dissipation constr aints, 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. App Note [2] PWB Layout Considerations - It is recommended to provide 100pF decoupling capacitors as close as possible to the pins of the device, with additional larger decoupling capacitors further away. For example, in the Recommended Layout shown below, there ar e 100pF 0402 capacitors placed very near the device pins, and 1uF 0805 capacitors placed further away (the gate line shown without a 1uF capacitor (pin 6) would have this capacitor further away on the other side of the screw). Thermal management of the device is essential. It is recommended that measures such as copper-filled vias under the package, and post/screws for top to bottom heat transfer are used (see Recommended Layout shown below). Adequate heat-sinking under the PWB is necessary in maintaining the package base at a safe operating temperature. App Note [3] Power Detector - As shown in the schematic at right, t he power detector is implemented by providing +5V bias and measuring the difference in output voltage with standard op-amp in a differential mode configuration.
