Recommended Operating Conditions

The Recommended Operating Conditions indicate the limits, inside which the device should be operated, to guarantee the performance given in Electrical Specifications. Operating outside these limits may not necessarily cause damage to the device, but the performance may degrade outside the limits of the electrical specifications. For limits, above which damage may occur, see Absolute Maximum Ratings.

Electrical Specifications

The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for a down conversion application with a +21dBm sine wave LO input. Min and Max limits apply only to our connectorized units and are guaranteed at TA=+25°C. All bare die are 100% DC tested and visually inspected.

^[1]^[2]^[3]^[4] Measured as an I/Q down converter. (i.e., I and Q powers are not combined)

^[5] Image Rejection and Single sideband performance plots are defined by the upper sideband (USB) or lower sideband (LSB) with respect to the LO signal. Plots are defined by which sideband is selected by the external IF quadrature hybrid.

^[6] Typical IIP3 measured with I and Q ports combined with an external quadrature hybrid coupler.

^[7]^[8] Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.

Typical Performance Plots

Due to limited available LO power, all performance plots are measured with a +21dBm LO drive and in most cases bandlimited to 45 GHz. Data is not representative of the performance of a properly operated unit. Linear performance at high frequency and high LO power is similar to MMIQ-1865H. See MMIQ-1865H datasheet for expected linear performance.

I output means that the IF output signal is measured at the I port of the mixer and the Q port is loaded. Q output means the IF output signal is measured at the Q port of the mixer while the I port is loaded.
