Port Configuration and Functions

Port Diagram

A top-down view of the MMIQ-0218L’s CH-1 package outline drawing is shown below. The mixer may be operated as either a downconverter or an upconverter. Use of the RF or IF as the input or output port will depend on the application. See Application Information for input and output port configuration for common applications.

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 +17 dBm sine wave LO input.

^[1] 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.

^[2] Mixer Noise Figure given for single sided I/Q conversion typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz. Image reject downconversion will show noise figure improvements in the presence of image noise.

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. SSB in phase input means that a low frequency quad hybrid is used to split the input, and the in-phase component is applied to the I port and the 90-degree component is applied to the Q port. SSB out of phase input means that a low frequency quad hybrid is used to split the input, and the in-phase component is applied to the Q port and the 90-degree component is applied to the I port.

⁵ I+Q measurements taken with an external quadrature hybrid attached to the I and Q ports of the mixer. Orientation depends on up conversion or down conversion measurement.
