^[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.

Typical Performance Plots

The test conditions and frequency plan below applies to all following sections, unless otherwise specified.

Mmiq 0218lsm Perf Plots Conditions

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.

Typical Spurious Performance: Downconversion

Typical downconversion spurious data is provided by selecting RF and LO frequencies (± m*LO ± n*RF) within the RF/LO bands, to create a spurious output at an IF of 91 MHz. The value of this spur is plotted against the RF input frequency below. Spurious suppression is scaled for different RF power levels by (n-1), where “n” is the RF spur order. For example, the 2RF x 2LO spur is 66 dBc for a -10 dBm input, so a -20 dBm RF input creates a spur that is (2-1) x (-10 dB) lower, or 76 dBc.

Typical Spurious Performance: Up-Conversion

Typical spurious data is taken by mixing an input IF at 91 MHz, with LO frequencies(± m*LO ± n*IF), to create a spurious output within the RF output band. The value of this spur is plotted against the RF Output Frequency. Spurious suppression is scaled for different IF input power levels by (n-1), where “n” is the IF spur order. For example, the 2IFx1LO spur is typically 32 dBc for a -10 dBm input with a sine-wave LO, so a -20 dBm IF input creates a spur that is (2-1) x (-10 dB) lower, or 42 dBc.
