FUNCTION
Power-Supply Connection. Bypass each V CC pin to GND with capacitors as shown in the Typical
Application Circuit .
Single-Ended 50 ? RF Input. This port is internally matched and DC shorted to GND through a balun.
Requires an external DC-blocking capacitor.
Center Tap of the Internal RF Balun. Bypass to GND with capacitors close to the IC, as shown in the
Typical Application Circuit .
Ground
Bias Resistor for Internal LO Buffer. Connect a 619 ? ± 1% resistor from LOBIAS to the power supply.
Local Oscillator Select. Logic control input for selecting LO1 or LO2.
Local Oscillator Input 1. Drive LOSEL low to select LO1.
Local Oscillator Input 2. Drive LOSEL high to select LO2.
External Inductor Connection. Short LEXT to ground using a 0 ? resistor. For applications requiring
improved RF-to-IF and LO-to-IF isolation, connect a low-ESR inductor from LEXT to GND. See the
Applications Information section regarding stability issues when using an LEXT inductor.
Differential IF Outputs. Each output requires external bias to V CC through an RF choke (see the
Typical Application Circuit ).
IF Bias Resistor Connection for IF Amplifier. Connect a 953 ? ± 1% resistor from IFBIAS to GND.
Exposed Ground Paddle. Solder the exposed paddle to the ground plane using multiple vias.
Detailed Description
The MAX9986A high-linearity downconversion mixer
provides 8.2dB of conversion gain and +25dBm of
IIP3, with a typical 10dB noise figure. The integrated
baluns and matching circuitry allow for 50 ? single-
ended interfaces to the RF and the two LO ports. A sin-
gle-pole, double-throw (SPDT) switch provides 50ns
switching time between the two LO inputs with 49dB of
LO-to-LO isolation. Furthermore, the integrated LO
buffer provides a high drive level to the mixer core,
reducing the LO drive required at the MAX9986A ’ s
