LTC5510
1MHz to 6GHz Wideband
High Linearity Active Mixer
Description
Demonstration circuit 1983A showcases the LTC®5510
wideband high linearity active mixer for both upconverting and downconverting applications. Its input port is
optimized for 30MHz to 3GHz, and its output port is
optimized for 1.2GHz to 2.1GHz. The LO input can be
either high side or low side.
Another demonstration circuit, the DC1984A, is designed
for evaluating the LTC5510 at the lower output frequency
range of 10MHz to 1.3GHz.

The LTC5510 is a high linearity active mixer optimized
for applications requiring very wide input bandwidth, low
distortion, and low LO leakage. The IC includes a doublebalanced active mixer with input buffer and a high speed
LO amplifier. The mixer can be used for both up- and
down-conversion and requires only 0dBm of LO power to
achieve excellent distortion and noise performance. The
LTC5510 is optimized for 5V but can also be used with
a 3.3V supply with reduced performance. The shutdown
function allows the part to be disabled for further power
saving.

DETAILED DESCRIPTION
Absolute Maximum Ratings
Enable Function
NOTE. Stresses beyond absolute maximum ratings may
cause permanent damage to the device. Exposure to any
absolute maximum rating condition for extended periods
may affect device reliability and lifetime.
The LTC5510 features Enable/Shutdown control. When
the applied Enable (EN) voltage is logic high (>1.8V), the
mixer is enabled. When the Enable (EN) voltage is logic
low (<0.5V), the mixer is shutdown reducing current
consumption to approximately 1.3mA. The Enable voltage
should never fall below –0.3V or exceed the power supply
voltage by more than 0.3V.
Supply Voltage Ramping
Fast ramping of the supply voltage can cause a current
glitch in the internal ESD protection circuits. Depending on
the supply inductance, this could result in a supply voltage transient that exceeds the maximum rating. A supply
voltage ramp time of greater than 1ms is recommended.
Do not clip powered test leads directly onto the demonstration circuit’s VCC and EN turrets. Instead, make all
necessary connections with power supplies turned off,
then increase to operating voltage.
Supply Voltage
The LTC5510 automatically detects the supply voltage and
configures internal components for 5V or 3.3V operation.
The auto-detect circuit switches at approximately 4.1V.
To avoid undesired operation, the mixer should only be
operated in the 4.5V to 5.3V or 3.1V to 3.6V supply range.
For best overall temperature performance, the external
bias adjustment resistor, R1, should be set to 4.75kΩ
for 5V supply and 1.8kΩ for 3.3V supply. By default,
demonstration circuit 1983A is configured for 5V supply
with R1 = 4.75kΩ pre-installed.
Temperature Monitor (Temp)
The LTC5510’s junction temperature can be estimated by
forcing a current into the on-chip diode and measuring
the resulting voltage:
10µA forced current:
TJ =
VD – 742.4
–1.796
80µA forced current:
TJ =
VD – 795.6
–1.609
Where TJ is the junction temperature in °C, and VD is the
TEMP pin voltage in mV.

Demonstration Circuit 1983A’s LO input port is broadband
matched to 50Ω from 5MHz to 6GHz, with better than 10dB
return loss. The impedance match is maintained whether
the part is enabled or disabled.
Demonstration Circuit 1983A utilizes a compact multilayer
chip hybrid balun at the output port. The output port is
well matched to 50Ω from 1.2GHz to 2.1GHz. The OUT
port can be re-matched for other frequencies. See the

Quick Start Procedure
Demonstration circuit 1983A is easy to set up to evaluate the performance of the LTC5510. Refer to Figure 4,
Figure 5, and Figure 6 for proper equipment connections.
NOTE. Care should be taken to never exceed absolute
maximum input ratings. Make all connections with RF
and DC power off.
Return Loss Measurements
1.Configure the Network Analyzer for return loss measurement, set appropriate frequency range, and set the test
signal to 0dBm.
2.Calibrate the network analyzer.
3.Connect all test equipment as shown in Figure 4 with
the DC power supply turned off.
4.Increase the DC power supply voltage to 5V, and verify
that the total current consumption is close to the figure
listed in the Performance Summary. The supply voltage
should be confirmed at the demo board VCC and GND
terminals to account for test lead ohmic losses.
5.Terminate unused demo board ports in 50Ω. Measure
return losses of the IN, LO and OUT ports.
RF Performance Measurements
1.Connect all test equipment as shown in Figure 5 with the
signal generators and the DC power supply turned off.

Measurement Equipment and Setup
The LTC5510 is a wideband active mixer IC with very high
linearity. Accuracy of its performance measurement is
highly dependent on equipment setup and measurement
technique. The recommended measurement setups are
presented in Figure 4, Figure 5, and Figure 6. The following precautions should be observed:
1.Use high performance signal generators with low harmonic output and low phase noise, such as the Rohde
& Schwarz SME06. Filters at the signal generators’
outputs may also be used to suppress higher-order
harmonics.
2.A high quality RF power combiner which provides
broadband 50Ω termination on all ports and have good
port-to-port isolation should be used, such as the MiniCircuits ZFSC-2-372-S+.
3.Use high performance amplifiers with high IP3 and high
reverse isolation, such as the Mini-Circuits ZHL-1042J,
on the outputs of the RF signal generators to improve
source isolation to prevent the sources from modulating
each other and generating intermodulation products.
4.Use attenuator pads with good VSWR on the demonstration circuit’s input and output ports to improve
source and load match to reduce reflections, which
may degrade measurement accuracy.
6.Use narrow resolution bandwidth (RBW) and engage
video averaging on the spectrum analyzer to lower the
displayed average noise level (DANL) in order to improve
sensitivity and to increase dynamic range. However, the
trade off is increased sweep time.
7.Spectrum analyzers can produce significant internal
distortion products if they are overdriven. Generally,
spectrum analyzers are designed to operate at their best
with about –30dBm at their input filter or preselector.
Sufficient spectrum analyzer input attenuation should be
used to avoid saturating the instrument, but too much
attenuation reduces sensitivity and dynamic range.
8.Before taking measurements, the system performance
should be evaluated to ensure that:
a. Clean input signals can be produced. The two-tone
signals’ OIP3 should be at least 15dB better than the
DUT’s IIP3.
b.The spectrum analyzer’s internal distortion is minimized.
c. The spectrum analyzer has enough dynamic range and
sensitivity. The measurement system’s IIP3 should be
at least 15dB better than the DUT’s OIP3.
d.The system is accurately calibrated for power and
frequency.
5.A high dynamic range spectrum analyzer, such as the
Rohde & Schwarz FSEM30, should be used for linearity
measurement.
