CHV2711-QJ

The CHV2711 internally pre-matched power HBT device provides 8 dB of gain, 2.5% EVM at 26.5 dBm output power for 802.16 OFDM signal with a peak to average power ratio of 9 dB. CHV2711-QJ 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. CHV2711-QJ 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. CHV2711-QJ operates with unique matching at each of the popular WiMAX bands with the inherent repeatability of an InGaP HBT process.
