Port Configuration and Functions

Port Diagram

A bottom-up view of the MMIQ-1867LSM’s SMT 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.

^[1]^[2]^[3]^[4]^[5]^[6] Measured as an I/Q down converter (i.e., I and Q powers are not combined)

^[7] 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.

^[8] Typical IIP3 is measured with I and Q ports combined with an external quadrature hybrid coupler in a down conversion.

^[9]^[10] Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.

Typical Performance Plots

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.
