U1019-QH
Features
Integrates Image Reject (Balanced) Mixer, LO Buffer, LO Doubler and RF Buffer 7 dB Conversion Gain (USB) -25 dBm (2x) LO Leakage (at RF Port) 26 dBm Output Third Order Intercept Point (OIP3) Variable Gain with Adjustable Bias 4x4mm QFN Package 100% RF and DC Testing
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.

37.0-40.0 GHz Up-Converter QFN, 4x4mm
January 2010 - Rev 27-Jan-10
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.

U1019-QH
App Note [3] Board Layout - As shown in the recommended board layout, it is recommended to provide 100pF decoupling capacitors as close to the bias pins as possible. Additional 10nF and 1uF on each of the bias lines are recommended placed a distance further away.
Recommended Board Layout
App Note [4] IF Bias - To obtain optimum 2xLO leakage performance, tuning is achieved by adjusting the DC bias on each of the IF inputs (IF1, IF2, IF1*, IF2*). DC bias is implemented by adding simple bias tees to each of the four IF ports. The diagram below shows a typical bias tee design used. If the IF1 and IF2 ports are used for the IF input, the IF1* and IF2* ports are DC biased and terminated into 50 . A typical tuning arrangement is to apply a fixed 0.3V DC bias to both the used IF input ports (i.e. IF1,IF2 or IF1*,IF2*). The remaining two IF ports which have been terminated to 50 tuning independently for minimum 2xLO leakage. For minimum 2xLO leakage in a system, it may be necessary to correct the IF DC bias for different frequency and temperature conditions. This can be implemented by calibration and offset tables stored in memory, and used to control IF bias over all practical conditions.

App Note [5] Extended IF Frequency Range - If using the XU1019-QH using IF frequencies greater than 2 GHz, conversion gain roll-off can be minimized by placing 1pF capacitors on each of the four IF ports. The capacitors should be placed close to the package, between the bias tees and the package.
