Name

Description

1-bit 6dB gain control for path 1. (Low/open = no attenuation; High = 6dB attenuation). A 500kΩ pull-down

resistor is connected between this input and GND.

ATT1_CTRL

STBY1

Standby (Low/open = path 1 power ON; High = path 1 power OFF). A 500kΩ pull-down resistor is connected

between this input and GND.

RF SWITCH 1 control (Low/open = select main RX PATH 1; High = termination). SW1_CTRL also puts path 1

into Standby Mode for minimum current consumption. A 500kΩ pull-down resistor is connected between this

input and GND.

Ground these pins.

Power supply. Bypass to GND with capacitors shown in the F0453B Application Circuit (see Figure 29) as close

as possible to pin.

SW2_CTRL

STBY2

RF SWITCH 2 control (Low/open = select main RX PATH 2; High = termination). SW2_CTRL also puts path 2

into Standby Mode for minimum current consumption. A 500kΩ pull-down resistor is connected between this

input and GND.

Standby (Low/open = path 2 power ON; High = path 2 power OFF). A 500kΩ pull-down resistor is connected

between this input and GND.

1-bit 6dB gain control for path 2. (Low/open = no attenuation; High = 6dB attenuation). A 500kΩ pull-down

resistor connects between this input and GND.

ATT2_CTRL

RX2_OUT

SW2_OUT

RF output path 2 matched to 50Ω. Use external DC block as close to the pin as possible.

RF2 switch output matched to 50Ω. Use external 50Ω terminating resistor with proper power rating as required

for the application.

SW2_IN

SW1_IN

RF2 switch input matched to 50Ω. Use external DC block as close to the pin as possible.

RF1 switch input matched to 50Ω. Use external DC block as close to the pin as possible.

RF1 switch output matched to 50Ω. Use external 50Ω terminating resistor with proper power rating as required

for the application

SW1_OUT

RX1_OUT

RF output path 1 matched to 50Ω. Use external DC block as close to the pin as possible.

Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple ground

vias to provide heat transfer out of the device into the PCB ground planes. These multiple via grounds are also

required to achieve the noted RF performance.
