General Description
The CHV2721-QJ is a high linearity single stage class AB
Heterojunction Bipolar Transistor (HBT) power amplifier
capable of 11 dB of gain, 8 Watt of power at 1 dB
compression and is housed in a 6X6mm QFN package. The
CHV2721-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 3.3 -3.6 GHz bands.

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.

• 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.

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.
