Description

This series of coaxial isolators from QUEST Microwave Inc. was developed to satisfy our customers' demand for high power applications in the 800 to 2000 MHz range. The sturdy design of these isolators is excellent for both commercial and military environments. The termination is placed inside the isolator to obtain maximum heat dissipation. Standard models are supplied with type N female connectors. Other connector types and higher power terminations are available upon request.

Please consult the factory for specific requirements.

Description

QUEST Microwave's coaxial isolators and circulators provide excellent performance over octave frequency hands. Standard models are supplied with SMA female connectors. The standard terminations are rated at 10 watts. Model SR0816T01 has a one watt termination due to the smaller package size.

To request a circulator, replace the T in the model number with a C.

Note: Various configurations, with different connector types and high power terminations, are available. Other octave bands are also available. Please consult the factory for custom requirements.
