Table 1. Pin DescriptionsNumberNameDescription123SW_LATCHRF_SELRF_INYStand-by latch. Pull Low or Ground for Normal Operation. If left floating, this input will be internally pulledhigh, disabling SPI writes to ENb (Standby) and RF SW bits (A0, A2).RF input selection. Pull high to select RF_INY. Pull low to select RF_INX.Alternate RF Input. Separated from RF_INX by internal SP2T. AC couple to this pin. This is a reflectiveswitch and is not internally matched to 50 ohms.4, 5, 6, 8,11,15, 21,22, 34, 367, 13, 29, 30,31, 32, 33GNDGround these Pins.NCNo Connection. Not internally connected. OK to connect to Vcc. Recommended Connection is Ground.9, 16, 25VCC10121417181920232426272835LO_ADJLO_INSTBYIF_BIAS_IIF_BIAS_QIF_I+IF_I-IF_Q-IF_Q+CSbDATACLKRF_INX— EPPower Supply. Bypass to GND with capacitors shown in the Typical Application Circuit as close aspossible to pin.Connect the specified resistor from this pin to ground to set the LO path ICC. This is a current settingresistor.LO Input. AC couple to this pin. Internally matched to 50 ohms.STBY Mode. Pull this pin high for Standby mode (~20 mA). Pull low or Ground for normal operation.Connect the specified resistor from this pin to ground to set the IF amplifier bias reference. This is NOT acurrent setting resistor.Connect the specified resistor from this pin to ground to set the IF amplifier bias reference. This is NOT acurrent setting resistor.In-Phase Positive Port Mixer Differential IF Output. Connect pullup inductors from each of these pins toVCC (see the Typical Application Circuit).In-Phase Negative Port Mixer Differential IF Output. Connect pullup inductors from each of these pins toVCC (see the Typical Application Circuit).Quadrature Negative Port Mixer Differential IF Output. Connect pullup inductors from each of these pinsto VCC (see the Typical Application Circuit).Quadrature Positive Port Mixer Differential IF Output. Connect pullup inductors from each of these pins toVCC (see the Typical Application Circuit).Chip Select Bar. The falling edge initiates a programming cycle and the rising edge latches theprogrammed shift register data into the active register.Serial Data Input.Serial Clock Input.Main RF Input. Separated from RF_INY by internal SP2T. AC couple to this pin. This is a reflectiveswitch and is not internally matched to 50 ohms.Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multipleground vias to provide heat transfer out of the device into the PCB ground planes. These multiplegrounds are also required to achieve the noted RF performance.© 2022 Renesas Electronics Corporation3February 7, 2022
