Termination
Insensitive Mixer covers the frequency range
of 10 to 2500 MHz using transmission line
hybrid junction techniques to isolate the diode
rings from termination mismatch-induced
reflections. This means the intermodulation
ratio is independent of the IF port impedance,
so this unit is ideal for applications where a
high performance mixer must drive a reactive
load (e.g., filter) at the IF port.
