ANT-CHA

RF Input to Channel A. The ANT-CHA pin is ac-coupled to 0 V and matched to 50 Ω.

Matching and a dc blocking capacitor are not required.

5

SWCTRL-CHAB

Control Voltage for Switches on Channel A and Channel B.

6

SWVDD-CHAB

Supply Voltage for Switches on Channel A and Channel B.

8

ANT-CHB

RF Input to Channel B. The ANT-CHB pin is ac-coupled to 0 V and matched to 50 Ω.

Matching and a dc blocking capacitor are not required.

12

TERM-CHB

Termination Output for Channel B. The TERM-CHB pin is the transmitter path for Channel B.

The TERM-CHB pin is ac-coupled to 0 V and matched to 50 Ω. No matching and dc blocking

capacitor required.
