3.3-3.8 GHz HFET 3W Linear Power Amplifier P1048-QJ December 2007 - Rev 03-Dec-07 Features P1dB, 3W Power Gain, 13 dB Positive Voltage Supply, +5V to +8V Output and Input Pre-Matched Internally Thermally Efficient for Higher MTTF RoHS Compliant 6X6mm QFN Ideal for WiMAX Applications (802.16) General Description The XP1048-QJ is a high linearity single stage power amplifier capable of 13 dB of gain, 3 Watt of power at 1 dB compression and is housed in a 6X6mm QFN package. The XP1048-QJ provides less than 2.5% EVM at 27 dBm output power with 802.16 OFDM signal and peak to average power ratio of 9.17 dB. The input and output of the device are pre-matched facilitating a simplified output matching approach. The quiescent current is controlled using a negative voltage. The high dynamic range of this device makes it ideal as a final or driver stage for WiMAX equipment in the 3.3-3.8 GHz bands.

Negative voltage supply (Vgg) needs to be turned on first and then positive voltage can be applied to the drain (Vdd). When turning off the device, the positive supply (Vdd) should be turned off first and then negative voltage (Vgg) can be removed. The gate voltage is adjusted in order to set the drain current to the desired level. The gate voltage required to achieve a certain current can vary over temperature and from one device to another due to pinch-off voltage variation. Constant drain current can be achieved by Implementing an active bias circuit which allows for temperature compensation and eliminates the effect of pinch-off voltage variation. Typical cost of such applications is $0.15.

As used herein: (1) Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. (2) A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. Package Attachment - This packaged product from Mimix Broadband is provided as a rugged surface mount package compatible with high volume solder installation. Care should be taken not to apply heavy pressure to the top or base material to avoid package damage. Vacuum tools or other suitable pick and place equipment may be used to pick and place this part. Care should be taken to ensure that there are no voids or gaps in the solder connection so that good RF, DC and ground connections are maintained. Voids or gaps can eventually lead not only to RF performance degradation, but reduced reliability and life of the product due to thermal stress. Mimix Lead-Free RoHS Compliant Program - Mimix has an active program in place to meet customer and governmental requirements for eliminating lead (Pb) and other environmentally hazardous materials from our products. All Mimix RoHS compliant components are form, fit and functional replacements for their non-RoHS equivalents. Lead plating of our RoHS compliant parts is 100% matte tin (Sn) over copper alloy and is backwards compatible with current standard SnPb low-temperature reflow processes as well as higher temperature (260°C reflow) “Pb Free” processes.
