MIDISCO offers an extensive line of single and dual junction coaxial isolators and circulators covering standard bands in narrow-band, octave and multi-octave frequency ranges up to 40 GHz. Drop-in units and units for cellular/PCS/PCN applications are also available. Waveguide isolators and circulators cover 12.4-18 GHz(WR62) and 18-26.5 GHz(WR42) in 10% bandwidths. Isolated waveguide flanges in 200 MHz bandwidths, as well as "Iso-Guide" waveguide to coaxial adapters that include integral isolators can also be supplied.
The M3I2640 isolator (replace the I with C in any part number for the equivalent circulator) covers the 26.5 to 40 GHz range with a typical isolation of 15 dB and an insertion loss of 0.8 dB. It is packaged in a compact 0.50 x 0.7 footprint. The M3I5964 covers 5.9 to 6.4 GHz with a typical isolation of 26 dB, an insertion loss of 0.1 dB, and a VSWR of 1.10:1. Coaxial units are normally supplied with nickel plating housings and a chemical film finish per MIL-C-5541B Class 3.
