Overview

The L3211 Barrel Booster has been specifically tailored for 

wireless camera back applications. Designed to fit directly 

onto the RF output from the Link range of transmitters, this 

unit is small, lightweight and easy to use. This amplifier 

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 filtering and a 

power save mode this amplifier 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.
