LO/IF Diplexer Includes a diplexer, a 1 m. mixer to diplexer cable, and necessary interface adapters. Diplexers available for Anritsu, Agilent/HP, IFR, Marconi, etc.  Specify manufacturer / model. Tektronix diplexer not available.
LO Freq.: Up to 18.6 GHz  (M42HW, K Band, up to 13.25 GHz).
LO Level: +12 to +15 dBm nom. at the mixer  (useable +6 to +18 dBm with degraded conversion loss).
Mixer Bias: 0 to 10 mA typical, 20 mA max.  Typically provided by the spectrum analyzer.  An adjustable DC current supplied thru a 1 kW resistor and a bias T will allow optimization of conversion loss for given LO power and frequency conditions.  If bias is not available in the user’s application, the mixer can utilize self bias if a DC return path is provided.  Optimization of the DC return resistance may be required for best performance.  A 1 dB pad in the IF path can serve as a DC return with possible degraded conversion loss.

All mixers tested for proper operation and delivered with a "Certificate of Conformance." Measured conversion loss data are included with all mixers up to 110 GHz using spectrum analyzer emulation data supplied by the analyzer manufacturer, see the list below for available emulations. Measured conversion loss data are not available above 110 GHz as there are no recognized power standards above 110 GHz for reference. The spectrum analyzer make and model must be identified on purchase order. Mixers covering above 110 GHz are tested for proper operation using an OML # 40200WGS source at two frequencies with Tek 2782 spectrum analyzer plots supplied. OML can not specify conversion loss as it is not possible to duplicate each type of spectrum analyzer. Conversion loss can vary with each individual spectrum analyzer.

Mixer conversion loss data is available only for the following spectrum analyzers.   The manufacturers of these analyzers have provided OML with emulation data for use with the "Oleson Microwave Labs Millimeter Wave Harmonic Mixer Test Set."

The OML harmonic mixers are useable with other instruments (older spectrum analyzers not listed, EIP counters, some surveillance receivers, etc).   The mixers are also useable in scientific applications such as radio astronomy, as phase locking mixers, etc.   OML can not provide conversion loss data for these applications.   There is not a "delete" price option for the conversion loss data.   Customers with these "non listed applications" can chose an analyzer from the above list that will have performance parameters similar to their application or OML will suggest a suitable test emulation if the customer will provide L.O. and I.F. data for his application.

Scientific Atlanta (S.A) receivers are specifically not included in the available test emulations.   S.A. utilized harmonic mixers in a very unusual manner. S.A. utilized the mixer diode self-generated bias current as a signal for their L.O. leveling loop. S.A. did not provide mixer conversion loss data when it sold mixers for this system. OML has no method for testing to this system design. Many users have reported excellent results using OML mixers in S.A. systems following the system's standard set-up and calibration procedure.

Notes: 1) Maximum power = 100 mW (RF + LO power).
2) Equivalent average noise level typical with a full spec. Tek. 2750 or 490 series Spectrum Analyzer using a 1 KHz RBW, with peaking optimized.
3) Mixers are compatible with the MIL.-F-3922/xx spec. flange. Insert the listed number for /xx.
4) Measured conversion loss data are not available above 110 GHz as there are no recognized reference standards available.
5) Because these mixers are passive components, receiving only LO power from customer-owned equipment, CE  testing is not required.
