RF Distribution Networks Combine Multiple Functions
Endwave Defense Systems, a manufacturer of RF subsystems and components for defense and homeland security applications, has announced the release of a series of custom multi-function assemblies (MFA) for RF power distribution applications. These particular MFAs provide input filtering, amplification using GaAs MMIC devices, digitally controlled attenuation and temperature compensated power distribution of incoming RF signals amongst eight output ports. Limiters and equalizers are incorporated onto each signal path to provide flat output power response vs. frequency, and particular care has been taken in the design to provide stringent phase matching and tracking performance. Multiple models have been developed to accommodate multi-octave bandwidths within the 0.5 to 18 GHz range, making them ideally suited for electronic surveillance and signal intelligence (SIGINT) applications. Each model is hermetically sealed and works over the complete military operating range of -55 to +85C.
