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 REF
IN
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.
