GaAs MMIC High Dynamic Range Mixer

MT3-0113SCQG

Page 1The MT3-0113SCQG is a triple balanced passive diode GaAs MMIC
mixer offering high dynamic range, low conversion loss, and excellent
repeatability. As with all T3 mixers, this mixer offers unparallelednonlinear performance in terms of IIP3, P1dB, and spurious performancewith a flexible LO drive requirement from +22 dBm to +30 dBm. The
MT3-0113SCQG is available in a surface-mount outline, or in an SMA
connectorized evaluation fixture. The MT3-0113SCQG is a superioralternative to Marki Microwave carrier and packaged T3 mixers, and isform-fit compatible with legacy T3’s in the CQ and CQG footprints.

Features Form-Fit Compatible with Legacy CQ and CQG T3 Mixers
 Broadband, Overlapping RF, LO and IF
 Suitable for Up or Down Conversion
 Compatible with Sine or Square-Wave LO Industry-Leading Spurious, IP3, and P1dB Performance Recommended LO Buffer Amplifier Module: ADM3-0022PA
 Application Note: T3 Mixer PrimerElectrical Specifications - Specifications guaranteed over -40 to +100C temperature range, measured in a 50Ω system.
Specifications are shown for Configurations A (B). See page 2 for port locations.

P1dB is typically within 1-2 dB of LO drive power.

3The typical value is for a +27 dBm LO. IP3 is dependent on LO drive and waveform. See plots and data sheet notes on page 5 for more details.

1. Configuration A/B refer to the same part number (MT3-0113SCQG) used in one of two different ways for optimal spurious performance. Forthe lowest conversion loss, use the mixer in Configuration A (port 1 as the LO input, port 3 as the RF input or output). If you need to use alower LO drive, use the mixer in Configuration B (port 1 as the RF input or output, port 3 as the LO input). For optimal spurious suppression,
experimentation or simulation is required to choose between Configuration A and B. For more information, see here.

I/O Connections & Ground Plane Finish is Gold Flash, 5 to 10 µ-inches, over Solderable Nickel, 100-200 µ-inches, over Cu.

Example Downconversion Spurious Suppression
The numbers shown in the chart below are for a 0 dBm RF input. Spurious suppression is scaled for different RF power
levels by (n-1), where “n” is the RF spur order. For example, the 2RFx2LO spur is 67 dBc for the A configuration for a 0dBm input with a sine-wave LO, so a -10 dBm RF input creates a spur that is (2-1) x (-10 dB) dB lower, or 77 dBc.

Example Upconversion Spurious Suppression
The numbers shown in the chart below are for a 0 dBm RF input. Spurious suppression is scaled for different RF power
levels by (n-1), where “n” is the RF spur order. For example, the 1LOx2IF spur is 56 dBc for the A configuration for a 0dBm input with a sine-wave LO, so a -10 dBm IF input creates a spur that is (2-1) x (-10 dB) dB lower, or 66 dBc.

DATA SHEET NOTES:
1. Mixer Conversion Loss Plot IF frequency is 100 MHz unless otherwise specified.
2. Mixer Noise Figure typically measures within 0.5 dB of conversion loss for IF frequencies greater than 5 MHz.
3. Conversion Loss typically degrades less than 0.5 dB at +100°C and improves less than 0.5 dB at -40°C.
4. Unless otherwise specified, sine-wave data is taken with +27 dBm LO drive.
5. Specifications are subject to change without notice. Contact Marki Microwave for the most recent specifications and data sheets.
6. Catalog mixer circuits are continually improved. Configuration control requires custom mixer model numbers and specifications.
