Description

Return loss bridges are useful in measuring VSWR, or return loss of filters, mixers, antennas and amplifiers. With directivity ratings of better then 45 dB, EAGLE bridges yield excellent results. The bridges may also be used for coupling two generators for intermodulation testing or power splitting for leveling systems. All EAGLE bridges have a true RF output; they can be connected directly to vector or spectrum analyzers. Even spectrum analyzers contained in communications service monitors can be used.

These bridges have three ports SOURCE, LOAD and REFLECTED. The REFLECTED port on all EAGLE bridges is an RF port. The bridge may be connected directly to a network or spectrum analyzer. The reference (a precision 50 ohm load) is built into EAGLE bridges so a REFERENCE port is not required.
