2.3-2.7 GHz InGaP HBT 8W Linear Power Amplifier
February 2008 - Rev 08-Feb-08
CHV2720-QJ
Features
P1dB, 8W Power Gain, 12 dB Efficiency, 25% @ 1W Positive Voltage Supply, +5V to +12V Integrated Active Bias Circuit Control Voltage Allows Different Current Settings Input Fully Matched Internally Output Pre-Matched Internally Thermally Efficient for Higher MTTF RoHS Compliant 6X6mm QFN Ideal for WiMAX and WiBRO Applications (802.16)
General Description
The CHV2720-QJ is a high linearity single stage class AB Heterojunction Bipolar Transistor (HBT) power amplifier capable of 12 dB of gain, 8 Watt of power at 1 dB compression and is housed in a 6X6mm QFN package. The CHV2720-QJ provides less than 2.5% EVM at 31dBm output power with 802.16 OFDM signal and peak to average power ratio of 9 dB. The input of the device is fully matched and the output is internally pre matched to 6 ohm facilitating a simplified output matching approach. This product operates off a single supply voltage between 5V and 12V and includes an internal bias circuitry to enable exact setting of quiescent current using an external control voltage. The device is ideal as a final or driver stage for WiMAX equipment in the 2.3 -2.7 GHz bands.

CHV2720-QJ
App Note [1] Biasing - The CHV2720-QJ requires power supply sequencing. Vcc should be applied first and then Vcontrol. Quiescent current (Icq) can be varied by adjusting Vcontrol in order to obtain the optimum performance desired. RF power is applied after both Vcc and Vcontrol are present. When turning off the device Vcontrol is switched off first and then Vcc. Vcontrol can be used to turn off the current.

Handling and Assembly Information
CAUTION! - Mimix Broadband MMIC Products contain gallium arsenide (GaAs) which can be hazardous to the human body and the environment. For safety, observe the following procedures: * Do not ingest. * Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical processing as these byproducts are dangerous to the human body if inhaled, ingested, or swallowed. * Observe government laws and company regulations when discarding this product. This product must be discarded in accordance with methods specified by applicable hazardous waste procedures. Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support devices or systems without the express written approval of the President and General Counsel of Mimix Broadband. 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. 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. Typical Reflow Profiles
