STE-KF610-11-S1-C is a W-band compact X6 frequency extender. The extender delivers frequency of 70 to 116 GHz with a typical output power of +10 dBm for an input signal within 11.6 to 18.33 GHz range. The extender has a typical harmonic suppression of -15 dBc. The compact design offers a practical solution for microwave frequency extension of synthesizers, such as Eravant models STL-SG-022203-S1 or SOT-02220313200-SF-B6. The input port configuration is a female K connector and the output is a WR-10 waveguide with a UG-387/U-M anti-cocking flange. Calibration data stored in the device memory can be directly accessed via USB-C cable. An AC to DC Power adapter and a Proxi-Flange™ Contactless Flange (STQ-WG-10010-FB-CF), is also included.
