Overview
The L3211 Barrel Booster has been specically tailored for
wireless camera back applications. Designed to t directly
onto the RF output from the Link range of transmitters, this
unit is small, lightweight and easy to use. This amplier
includes ALC (Automatic Level Control) in order to provide
a constant RF output power for all transmitter power level
settings. The L3211 has a wide DC operating range (9-28V)
and can be powered via the RF input connector* or using the
Lemo power cables supplied with the unit. These power cables
allow the option to connect to the Lemo power socket on the
wireless transmitter or to the D-Tap adaptor from an IDX or
Anton Bauer battery plate.
Incorporating LDPD (Link Digital Pre-Distortion) for improved
adjacent channel rejection, integral harmonic ltering and a
power save mode this amplier is a must have addition to any
wireless camera system where extended range is required.
* Switchable phantom power to the L3211 barrel booster is
provide in the L1530-1927 RF module.
