EVALUATION BOARD HARDWARE

The EV-RADAR-MMIC2 evaluation board requires an SDP-S or

SDP-B motherboard to program the device. These SDP boards are

not included with the evaluation board and must be purchased

separately.

POWER SUPPLIES

The EV-RADAR-MMIC2 evaluation board is powered via one

external supply of 5 V connected to VSUPPLY as described in the

Quick Start Guide section.

The EV-ADAR-D2S board is powered via two external supplies:

+9 V connected to VPOS and −9 V connected to VNEG, as

described in the Quick Start Guide section.

INPUT SIGNALS

The on-board, 100 MHz temperature compensated crystal

oscillator (TCXO) provides the necessary reference signal. Use

an external REFIN signal, if desired.

RADIO FREQUENCY (RF) INPUT SIGNALS

The RF input pins on the ADF5904 contain a dc bias voltage

and must be ac-coupled to the EV-RADAR-MMIC2 evaluation

board. The RF inputs are on the J2 (RX1_RFIN), J3 (RX2_RFIN),

J4 (RX3_RFIN), and J6 (RX4_RFIN) SMA connectors.

RF OUTPUT SIGNALS

The Tx outputs from the ADF5901 contain a dc bias voltage

and must be ac-coupled. The Tx outputs are available on the

J8 (TX_OUT1) and J9 (TX_OUT2) output SMA connectors.

CHANNEL MAPPING

Table 1 shows the pin mapping from the ADF5904 RXx_xx to

baseband outputs on the EV-ADAR-D2S evaluation board.
