Figure 2. Evaluation Board Configuration
The ADMV1013-EVALZ evaluation board contains a built in
ADMV1013 chip. Figure 2 shows the location of this chip on the
ADMV1013-EVALZ evaluation board and the block diagram of
the
ADMV1013 . The local oscillator (LO) input path shown in
Figure 3 operates from 5.4 GHz to 10.25 GHz with an LO
amplitude range of −6 dBm to +6 dBm. The LO input path also
has an internal quadrupler and a programmable band-pass
filter. Program the LO band-pass filter from QUAD_FILTERS
(Register 0x09, Bits[3:0]).
The LO path operates differentially or single-ended. LOP and
LON are the inputs to the LO path. Switch the LO path from
differential to single-ended, or vice versa, by setting the
QUAD_SE_MODE (Register 0x09, Bits[9:6]) through the serial
peripheral interface (SPI). Refer to the
ADMV1013 data sheet
for the appropriate setting.

Figure 3. LO Input Path Block Diagram
The ADMV1013-EVALZ evaluation board has two IF inputs,
IF_I and IF_Q, for single sideband upconversion, and four
I/Q inputs, I_P, I_N, Q_P, and Q_N, for direct conversion from
I/Q to RF. To evaluate the device in IF mode, connect the IF
inputs to a frequency generator through a 90° hybrid. To
evaluate the device in IF mode, the I/Q inputs must be kept
floating without the jumper, in this case Jumper J1 to Jumper J4.
To evaluate the device in I/Q mode, connect the I/Q inputs, I_P,
I_N, Q_P, and Q_N, to an I/Q baseband generator, and use Jumper
J1 to Jumper J4 with the I/Q inputs. The ADMV1013-EVALZ
evaluation board operates on a 5 V dc supply. Figure 4 shows the
top view of the ADMV1013-EVALZ evaluation board, and is for
evaluation purposes only with no implied guarantee of
performance or reliability.
