MADC-011010 Down Converter 37 - 40 GHz Rev. V3 Features Functional Schematic Description The MADC-011010 is an integrated LSB/USB receiver that has a noise figure of 3.8 dB and a typical conversion gain of 13 dB. The device integrates a four stage LNA followed by an image rejection mixer, and includes an integrated LO quadrupler and buffer amplifier within a 4 mm QFN package. The I/Q and complementary I*/Q* mixer outputs are provided, and two external 180 hybrids and one external 90 hybrid are required to complete the image rejection function.

Handling Procedures Please observe the following precautions to avoid damage: Static Sensitivity These electronic devices are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. Biasing Quickstart Turn ON: Step 1: Turn on the fixed voltage on VG4 first. Step 2: Turn on VG1, VG2 and VG3 at approximately -1.0V . Step 3: Turn on IF voltages at the fixed voltage. Step 4: Turn on VD1, VD2 and VD3 at the fixed voltages, and adjust corresponding VG to get the required current levels. Turn OFF: Reverse steps indicated in Turn ON sequence For further details please see App Note [1] 3 MACOM Technology Solutions Inc.

V3 App Note [1] Biasing MADC-011010 is operated by biasing VD1, VD2 and VD3 at +3.0 V. The corresponding drain currents are set to 30 mA, 100 mA and 150 mA respectively. V G4 requires a fixed voltage bias of nominally -2.5 V and all IF to be biased at +0.3 V. It is recommended to use active bias on V G1, 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] IF Outputs For highest gain, best image rejection and lowest noise figure all 4 IF ports should be used. I/I* and Q/Q* will be combined through two 180 hybrid couplers generating inphase and quadrature phase components. Inphase and quadrature signals then need to be combined through 90 hybrid combiner to create IF output. See App Note [4] for IF bias.

V3 App Note [3] Board Layout As shown in the recommended board layout, it is recommended to provide 100 pF decoupling capacitors as close to the bias pins as possible. Additional 10 nF and 1 F on each of the bias lines are recommended placed a distance further away. Recommended Board Layout App Note [4] IF Bias To obtain optimum OIP3 performance, it is required to apply DC bias of + 0.3 V on each of the IF inputs (I, Q, I*, Q*). This can be implemented by adding simple bias tees to each of the four IF ports (see drawing from App Note [2] for the bias tees location). The diagram below shows a typical bias tee design used.
