1MHz to 6GHz Wideband
High Linearity Active Mixer
FEATURES
DESCRIPTION
TheLTC®5510isahighlinearitymixeroptimizedforapplica-
tions requiring very wide input bandwidth, low distortion,
and low LO leakage. The chip includes a double-balanced
activemixerwithaninputbufferandahighspeedLOampli-
fier. The input is optimized for use with 1:1 transmission-
line baluns, allowing very wideband impedance matching.
The mixer can be used for both up- and down-conversion
and can be used in wideband systems.

Shutdown Control
The LO can be driven differentially or single-ended and
requiresonly0dBmofLOpowertoachieveexcellentdistor-
tion and noise performance, while also reducing external
drive circuit requirements. The LTC5510 offers low LO
leakage, greatly reducing the need for output filtering to
meet LO suppression requirements.

APPLICATIONS
The LTC5510 is optimized for 5V but can also be used
with a 3.3V supply with slightly reduced performance.
The shutdown function allows the part to be disabled for
further power savings.

PIN FUNCTIONS
TEMP(Pin1):TemperatureMonitor.Thispinisconnected
to the anode of a diode through a 30Ω resistor. It may be
used to measure the die temperature by forcing a current
into the pin and measuring the voltage.
I
(Pin 8): Bias Adjust Pin. This pin allows adjustment
ADJ
of the internal mixer current by adding an external pull-
down resistor. The typical DC voltage on this pin is 1.8V.
If not used, this pin must be left floating.
+
–
IN , IN (Pins2, 3):DifferentialSignalInput. Foroptimum
performance,thesepinsshouldbedrivenwithadifferential
signal. The input can be driven single-ended, with some
performance degradation, by connecting the undriven pin
to RF ground through a capacitor. An internally generated
1.6V DC bias voltage is present on these pins, thus DC
blocking capacitors are required.
GND (Pins 9, 12, 13, Exposed Pad (Pin 17)): Ground.
These pins must be soldered to the RF ground plane on
the circuit board. The exposed metal pad of the package
provides both electrical contact to ground and a good
thermal contact to the printed circuit board.
–
+
OUT , OUT (Pins 10, 11,): Differential Output. These
pins must be connected to a DC supply through imped-
ance matching inductors and/or a transformer center-tap.
Typical DC current consumption is 32mA into each pin.
LGND (Pin 4): DC Ground Return for the Input Amplifier.
This pin must be connected to DC ground. The typical
current from this pin is 64mA. In some applications an
external chip inductor may be used. Note that any induc-
tor DC resistance will reduce the current through this pin.
–
+
LO , LO (Pins 14, 15): Differential Local Oscillator Input.
A single-ended LO may be used by connecting one pin to
RF ground through a DC blocking capacitor. These pins
are internally biased to 1.7V; thus, DC blocking capacitors
are required. Each LO input pin is internally matched to
50Ω for both EN states.
EN(Pin5):EnablePin. Whentheappliedvoltageisgreater
than1.8V, theICisenabled. Below0.5V, theICisdisabled.
V
, V
(Pins 6, 7): Power Supply Pins for the Bias
CC2
CC1
and LO Buffer Circuits. Typical current consumption is
41mA. These pins should be connected together on the
circuit board and decoupled with a 10nF capacitor located
close to the pins.
TP (Pin 16): Test Pin. This pin is used for production test
purposes only and must be connected to ground.

APPLICATIONS INFORMATION
TheLTC5510useswidebandhighperformanceRFandLO
amplifiersdrivingadouble-balancedmixercoretoachieve
frequencyup-ordown-conversionwithhighlinearityover
a very broad frequency range. For flexibility, all ports are
differential; however, the LO port has also been optimized
for single-ended use. Low side or high side LO injection
can be used. The IN port may also be driven single-ended,
though with some reduction in performance.
external components required for the data sheet specified
performance are shown in Figures 1 and 2. The evaluation
boards are shown in Figures 3a and 3b.
The High Frequency Output test circuit, shown in Figure 1,
utilizes a multilayer chip balun to realize a single-ended
output. The Low Frequency Output test circuit in Figure 2
usesawire-woundbalunandisdesignedtoaccommodate
a differential output if desired. Both the IN and LO ports
are very broadband and use the same configurations for
both test circuits. Additional components may be used
to modify the DC supply current or frequency response,
which will be discussed in the following sections.

Figure 4a. The IN and IN pins drive the bases of the input
transistors while internal resistors are used for impedance
matching. These pins are internally biased to a common
mode voltage of 1.6V, thus external capacitors C1 and C2

3a. High Frequency Output Board (DC1983A)
The typical return loss at the IN port is shown in Figure 5
with 0.1µF at C1 and C2. The performance is better than
12dB up to 2.6GHz without C3. Adding a capacitance of
0.7pF at C3 extends the impedance match to 3GHz.
Differential input impedances (parallel equivalent) for
various frequencies are listed in Table 1. At frequencies
below 30MHz additional external components may be
needed to optimize the input impedance. Figure 4b shows
an equivalent circuit that can be used for single-ended
or differential impedance matching at frequencies below
1GHz. Above 1GHz, the S-parameters should be used.
TheDCbiascurrentoftheinputamplifierflowsthroughPin
4 (LGND). Typically this pin should be directly connected
to a good RF ground; however, at lower input frequencies
it may be beneficial to insert an inductor to ground for
improved IP2 performance. The inductor should have low
resistance and must be rated to handle 64mA DC current.

The LTC5510 can be driven by a single-ended or differ-
ential LO signal. Internal resistors, as shown in Figure 6,
provide an impedance match of 50Ω per side or 100Ω
differential. The impedance match is maintained when the
part is disabled as well. The LO input pins are internally
biased to 1.7V, thus external capacitors, C4 and C5 are
used to provide DC isolation.

in Figure 7 for C4 and C5 values of 0.1µF. The return loss
is better than 10dB from 5MHz to 6GHz. For frequencies
below 5MHz, larger C4 and C5 values are required. Table

baluns at the output. This board is intended for frequen-
cies above about 800MHz (limited by balun availability).
These baluns deliver good performance and are smaller
than wire-wound baluns. The board is configured for the
matching topology shown in Figure 10. Inductors L1 and
L2 are used to tune out the parasitic output capacitance,
whilethetransformerprovidesdifferentialtosingle-ended
conversion and impedance transformation. The DC bias
to the mixer core can be applied through the matching
inductors. Each pin draws approximately 32mA of DC
supply current.

The OUT and OUT pins are open collector outputs with
internal load resistors that provide a 245Ω differential
output resistance at low frequencies.

Temperature Monitor (TEMP)
Supply Voltage Ramping
The TEMP input (pin 1) is connected to an on-chip diode
that can be used as a coarse temperature monitor by forc-
ingcurrentintoitandmeasuringtheresultingvoltage. The
temperature diode is protected by a series 30Ω resistor
and additional ESD diodes to ground.
Fast ramping of the supply voltage can cause a current
glitchintheinternalESDprotectioncircuits.Dependingon
the supply inductance, this could result in a supply volt-
age transient that exceeds the maximum rating. A supply
voltage ramp time of greater than 1ms is recommended.
The TEMP pin voltage is shown as a function of junction

the 5V Wideband Up/Downmixer application. Results
are shown for frequencies up to 15GHz. The spur fre-
