They employ a dual-diode design to achieve flat-frequency response and low conversion loss. These are achieved without external dc bias or tuning stubs. Manual operation and computer-controlled hardware operation are simplified because mixer bias and tuning adjustments are not required. 261 HP 11970 Series HP 11974 Series HP 11970 series harmonic mixers are available in six bands HP 11970, 11974 Series Mixers HP model Noise Frequency LO level (dB) Freq.1 range harm Conversion 1 kHz response (GHz) number loss (dB) RBW (dB) Gain compression (dBm) 11970K 11970A 11970Q 11970U 11970V 11970W 18 to 26.5 26.5 to 40 33 to 50 40 to 60 50 to 75 75 to 110 -3 -5 -7 -7 -3 -1 1 HP 11974 Series Preselected Millimeter Mixers Eliminate the need for signal identification at millimeter frequencies. The HP 11974 series mixers are preselected from 26.5 to 75 GHz for faster, easier testing of millimeter devices and systems. Preselection reduces mixer overload from broadband signals and reduces radiation of local oscillator harmonics back to the device-under-test. Equipment operators can quickly locate true signals, and software development for automated measurements is greatly simplified. These mixers feature advanced barium-ferrite technology and come with a standalone power supply. They are particularly useful for broadband millimeter signal analysis, millimeter electromagneticinterference (EMI) measurements, and unattended monitoring of millimeter signals.
