RF2411 LOW NOISE AMPLIFIER/MIXER RoHS Compliant & Pb-Free Product Package Style: SOIC-14 LNA Features     N O  N GND 4 11 VCC2 GND 5 MIXER 10 RF IN- IF OUT+ 6 9 RF IN+ RF AMP IF OUT- 7 8 LO IN EW Functional Block Diagram Product Description N 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 balanced 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 interstage 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 conserve power.

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. LN A IN 3 4 5 6 GND GND GND IF OUT+ Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. Same as pin 2. Same as pin 2. Same as pin 2. Balanced open collector output of the mixer. External bias needs to be supplied to this pin. This can be done with a resistor to VCC (see application 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 application schematic, “1800MHz, Single-Ended Resistive Output Matching”). When using a resistor to VCC the resistor value will set the output impedance. Typical values for this resistor are 200 to 1k. A shunt inductor/capacitor resonator to VCC is needed to maintain proper DC voltage at the mixer. At low resistor values the resonator may be omitted 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 Matching with Balun” is recommended. Using both outputs and matching them correctly to a single ended load will result in a 6dB gain improvement over the plain single ended configuration. Same as pin 6 except complementary output. See pin 6. S GND ES IG N 2 IF OUTLO IN 50 mixer LO input. This pin has an internal pull-up resistor to VCC and 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. RF 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 applications 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 0.01F will be required if no other low frequency 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. 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com.
