Help with RF Isolators and RF Circulators specifications:

General Specifications
   Component Type       
   Your choices are...         
   Isolator       A device that permits a signal to pass in one direction while providing high isolation to reflected energy in the reverse direction. 
   Circulator       A passive device consisting of three or more ports that allows the signal entering each port to pass to the port adjacent to it (either clockwise or counter-clockwise) but not to the port in the other direction. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Configuration       
   Your choices are...         
   Coaxial       The RF component is designed for use with a coaxial cable. 
   Waveguide       The RF component is designed for use with a waveguide. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Performance
   Frequency Range:       The range of frequencies through which the isolator or circulator can operate. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Isolation:       The isolation from port A to port B of a device is defined as the degree of attenuation of the signal at port A measured at the B port with all other ports properly terminated.  Isolation is expressed in dB. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Insertion Loss:       The total RF power transmission loss resulting from the insertion of a device in a transmission line. It is defined as the ratio of signal power at the output of the inserted device to the input signal power at the input of the inserted device.  
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   VSWR:       When there are impedance mismatches in a system, some energy transmitted through will be reflected back to the source. Different amounts of energy will be reflected back depending on the frequency of the signal.  VSWR (Voltage Standing Wave Ratio) is a unitless ratio ranging from 1 to infinity, expressing the amount of reflected energy.  A value of one indicates that all the energy will pass through, while any other value indicates that a portion of the energy will be reflected. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Operating Temperature:       The operating temperature of the isolator or circulator. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
