Power Amplifier Chassis
US Patent:
8411447, Apr 2, 2013
Filed:
Dec 18, 2009
Appl. No.:
12/642160
Inventors:
Stephen D. Turner - State College PA, US
Assignee:
Teledyne Paradise Datacom, LLC - Thousand Oaks CA
International Classification:
H05K 5/00
US Classification:
361730, 361752, 361800, 361753
Abstract:
A power amplifier chassis for an n+1 redundant power amplifier system. The power amplifier chassis includes an embedded controller and a power amplifier. The embedded controller operates the power amplifier chassis in a master controller mode or a slave controller mode. When operated in the master controller mode, the embedded controller monitors operating parameters associated with the power amplifier chassis, and can transfer control of the power amplifier system when the embedded controller senses that the monitored operating parameters indicate a failure or impending failure of the power amplifier chassis. When operated in the slave controller mode, the embedded controller receives control instructions from the master controller power amplifier module, and is enabled to reconfigure the power amplifier chassis from the slave controller mode to the master controller mode in response to a failure or imminent failure indication of a first power amplifier chassis operated in master controller mode.

US Patent:
8189338, May 29, 2012
Filed:
Dec 18, 2009
Appl. No.:
12/641967
Inventors:
Stephen D. Turner - State College PA, US
Assignee:
Paradise Datacom, LLC - State College PA
International Classification:
H05K 5/00, H03F 3/68
US Classification:
361730, 330124 R
Abstract:
A modular power amplifier system includes power amplifier modules removably mounted within a cabinet. Each of the power amplifier modules includes an embedded controller and a power amplifier. An RF distribution panel includes an input port for receiving an RF input signal, and a signal splitter for dividing the RF input signal for input to the plurality of power amplifier modules. Coaxial dividers are configured to divide the RF input signal substantially equally between the plurality of power amplifier modules. Passive waveguide combiners are configured to combine the amplified RF output signals from the plurality of power amplifier modules at an output port to provide an RF output signal. A designated master controller monitors operating parameters associated with each power amplifier module. The combined power rating of the power amplifier modules exceeds a rated power of the system by at least one power amplifier module.
