The RF2411 is a monolithic integrated UHF receiver
front-end. The IC contains all of the required components
to implement the RF functions of the receiver except for
the passive filtering and LO generation. It contains an
LNA (low-noise amplifier), a second RF amplifier, and a
balanced mixer which can drive a single-ended or bal-
anced load. The output of the LNA is made available as a
pin to permit the insertion of a bandpass filter between
the LNA and the RF/Mixer section. The LNA output is
buffered to permit a wide range of choices for the inter-
stage filter without altering the VSWR or noise figure at
the LNA input and to provide high isolation from the LO to
the input port. The LNA section may be disabled to con-
serve power.

Pin

Function Description
Interface Schematic
This pin is NOT internally DC-blocked. An external blocking capacitor
must be provided if the pin is connected to a device with a DC path. A
value of 100pF is recommended for 900MHz and 22pF for 1800MHz.
LNA IN

and connect immediately to ground plane.

Balanced open collector output of the mixer. External bias needs to be
supplied to this pin. This can be done with a resistor to V (see appli-
IF OUT+
CC
cation schematic, “1800MHz, Balanced Resistor Output Matching”),
with a balun (see application schematic, “1800MHz, Output Matching
with Balun”) or when used in a single-ended configuration (see applica-
tion schematic, “1800MHz, Single-Ended Resistive Output Matching”).
IF OUT+
IF OUT-
When using a resistor to V the resistor value will set the output
CC
impedance. Typical values for this resistor are 200Ω to 1kΩ. A shunt
inductor/capacitor resonator to V is needed to maintain proper DC
CC
voltage at the mixer. At low resistor values the resonator may be omit-
ted at the expense of gain, output power and IP3. To obtain maximum
gain and output power a balun as shown in application schematics
“1800MHz, Output Matching with Balun” and “850MHz, Output Match-
ing with Balun” is recommended. Using both outputs and matching
them correctly to a single ended load will result in a 6dB gain improve-
ment over the plain single ended configuration.

Same as pin 6 except complementary output.
See pin 6.

LO IN
50Ω mixer LO input. This pin has an internal pull-up resistor to V and
CC
is not DC-blocked. An external blocking capacitor must be provided if
the pin is connected to a device with a DC path. A value of 100pF is
recommended for 900MHz and 22pF for 1800MHz.
LO IN
Balanced mixer RF Input port. This pin is NOT internally DC-blocked.
An external blocking capacitor must be provided if the pin is connected
to a device with a DC path. A value of 100pF is recommended for
900MHz and 22pF for 1800MHz. Matching is required; see the appli-
cations schematics. To minimize the noise figure it is recommended to
have a bandpass filter before this input. This will prevent noise at the
image frequency from being converted to the IF.

Supply Voltage for the LNA only. A 47pF external bypass capacitor is
required and an optional 0.01µF will be required if no other low fre-
quency bypass capacitors are nearby. The trace length between the pin
and the bypass capacitors should be minimized. The ground side of the
bypass capacitors should connect immediately to ground plane.
