General Description
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. 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.
