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.
