Pin Descriptions

Number

Name

Description

1

ATT1_CTRL 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.

2

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.

3

SW1_CTRL

RF SWITCH 1 control (Low /open = select main RX PATH 1; High = switch output). 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.

GND

Ground these pins.

6

SW2_CTRL

RF SWITCH 2 control (Low /open = select main RX PATH 2; High = switch output). 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.

7

STBY2

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

between this input and GND.

8

ATT2_CTRL 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.

10

RX2_OUT

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

12, 14, 27, 29

VDD

Power supply. Bypass to GND with capacitors shown in the F0452C Application Circuit as close as possible to

the pins.

16

SW2_OUT

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

for the application.

18

SW2_IN

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

23

SW1_IN

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

25

SW1_OUT

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

required for the application.

31

RX1_OUT

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

20, 21

NC

These pins can be left unconnected, or be connected to ground (recommended). Use a via as close to the pin

as possible if grounded.

―

EPAD

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 specified RF performance.
