Pin No.

Mnemonic

Description

Chip Select Bar. CS is used to activate the SPI port on the ADAR2001 and is active low.

When CS goes high, the data previously clocked into the shift registers is latched to the

chip. Connect a 200 kΩ pull-up resistor to 1.8 V from CS to ensure that the SPI interface is

deactivated when not in use.

SDO

Serial Data Output. Register states can be read back on the SDO line if Register 0x000,

Bits[4:3] are set high.

RFOUT4+, RFOUT4−,

RFOUT3+, RFOUT3−,

RFOUT2−, RFOUT2+,

RFOUT1−, RFOUT1+

Differential RF Outputs. RFOUTx± are 100 Ω differential pairs, ac-coupled internally.

RFOUTx± operate from 10 GHz to 40 GHz. All eight lines must have equal electrical and

mechanical lengths.

EPAD

Exposed Pad. The exposed pad must be connected to a ground plane with low thermal

and electrical impedance.
