General Description
The CHV2710 internally pre-matched power HBT device provides 9.5dB of gain, 2.5% EVM at 30dBm output power for 802.16 OFDM signal with a peak to average power ratio of 9.5dB. The device operates off a single supply voltage up to 12V and includes internal bias circuitry to enable exact setting of the quiescent current using an external Vcontrol. This Vcontrol is non-unique voltage setting and the same value can be used for each part depending on the required Icq. The device is ideal for high linearity, high data rate applications such as WiMAX. Internal pre-matching facilitates a simplified external matching approach and the highest in-band gain potential of the device. The device operates with unique matching at each of the popular WiMAX bands with the inherent repeatability of an InGaP HBT process.

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% matt tin (Sn) over copper alloy and is backwards compatible with current standard SnPb low-temperature reflow processes as well as higher temperature (260C reflow) "Pb Free" processes. For those customers not making the change at this time, Mimix will maintain production of current configurations. For questions and comments e-mail: ourearth@mimixbroadband.com.
