Typical LO Input Power Requirement : +13 dBm

Options Available:

diode bias for operations with low L.O. power micrometer driven tuners integrated IF amplifier custom units

Ordering Information

Also specify the following: LO frequency range Flange patterns ( if non standard ) IF frequency range IF connector ( if other than SMA )

Example:   To order a Subharmonically Pumped Mixer for operation at an RF frequency of 175 GHz to 181 GHz and 185                         GHz to 191 GHz in WR-5 waveguide, with an LO frequency of 183 GHz in WR-10 waveguide, an IF frequency                        of  2.0 GHz to 8.0 GHz, and a maximum DSB noise figure of 11 dB, specify : ZSM 5-10/11/183-5/6.
