General Description
Mimix Broadband’s 37.0-40.0 GHz GaAs MMIC Intergrated
Up-converter that has a typical conversion gain of 7 dB, and
an image rejection of greater than 15 dBc. It has been
optimized for USB operation. The device includes a LO
doubler and buffer, and can be tuned to give 2xLO leakage of
less than -25 dBm. Variable gain regulation can be achieved
by adjusting the bias, with turn-down trajectories optimized
to maintain linearity and minimal 2xLO leakage over the gain
control range. At full gain, an OIP3 of 26 dBm is typical. The
device comes in an RoHS compliant 4x4mm QFN surface
mount package offering excellent RF and thermal properties.
Typical application for this device are as an up-converter
stage in a linear 38GHz radio transmit lineup. They device is
well suited for Millimeter-wave Point-to-Point Radio, LMDS,
SATCOM and VSAT applications.

U1019-QH
App Note [1] Biasing
- As shown in the Pin Designations table, the device is operated by biasing Vd1, Vd2, and Vd3 at 4.0V. The corresponding
drain currents are set to 120mA, 120mA, and 150mA respectively. Vg4 requires a fixed voltage bias of nominally -3V. It is recommended to use
active bias on Vg1, Vg2, Vg3 to keep the currents in Vd1, Vd2, and Vd3 constant, in order to maintain the best performance over temperature.
Depending on the supply voltages available and the power dissipation constraints, the bias circuits may include a single transistor or a low power
operational amplifier, with a low value resistor in series with the drain supply to sense the current. Make sure to sequence the applied voltage to
ensure negative gate bias is available before applying the positive drain supply.
App Note [2] IF1/IF2 versus IF1*/IF2*
- The IF input to the typical configuration is through a 90deg hybrid coupler. The hybrid splits the IF input
into inphase and quadrature phase components. These two signals enter the XU1019-QH on either the IF1/IF2 pair, or the IF1*/IF2* complimentary
pair. Which ever pair are not used must be terminated into 50 ohms. There are subtle differences between the performance when using the main IF
ports (IF1,IF2) versus the complimentary ports (IF1*, IF2*) which are shown in the preceding performance curves. For highest gain, best image
rejection and lowest noise figure, the complimentary ports (IF1*, IF2*) should be used.
