APPENDIX C
Phase Combination using the Compact Redundant Combiner Assembly (CRCA)
If there is a requirement to provide two amplifiers with phase combination to give increased
power at the antenna, the N6145 controller is required as shown below. With the amplifiers
connected in this way, an RF INHIBIT will be generated as the CRCA waveguide switch
changes position.
