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.
The MADC-011010 is ideally suited for 38 GHz band
point to point radios.
Each device is 100% RF tested to ensure
performance compliance.

6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. MACOM does not recommend sustained operation near these
survivability limits.
8. Operating at nominal conditions with TJ ≤ +150°C will ensure
MTTF > 1 x 106 hours.
9. Junction Temperature (TJ) = TC + Өjc * (V * I)
Typical thermal resistance (Өjc) = 44°C/W.
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

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. VG4 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 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] 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.

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 µF 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. Before applying a
