Device Overview

General Description

MMIQ-0218H is a low LO drive, passive GaAs MMIC IQ mixer that operates across a 9:1 bandwidth. This is an ultra-broadband mixer spanning 2 to 18GHz on the RF and LO ports with an IF from DC to 3 GHz. Up to 40 dB of image rejection is available due to the excellent phase and amplitude balance of its on-chip LO quadrature hybrid. Both wire bondable die and connectorized modules are available.

Typical Harmonic Performance

RF/IF harmonics are measured with a fixed LO of 6.337 GHz at 23 dBm. Note that LO/IF/RF Harmonics are measured across more than the operating band of the mixer. LO Harmonics are not provided due to the lack of a low harmonic, high power LO source. For an estimate of LO harmonic bleedthrough see the MMIQ-0218L datasheet.

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 75 dBc for a -10 dBm input, so a -20 dBm RF input creates a spur that is (2-1) x (-10 dB) lower, or 85 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 22 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 32 dBc.
