AD6122 Evaluation Board

The IF output port impedance match used during characteriza-

tion at Analog Devices is as follows:

The AD6122 Evaluation Board consists of an AD6122, I/O con-

nectors, a 20-pin dual header, 2-pin headers and four AD830

high speed video difference amplifiers. It allows the user to

evaluate the AD6122’s IF amplifier and modulator together or

separately. Because the AD6122 may be used at any IF from 50

MHz to 350 MHz, pads are provided on the LOIPP input,

TXOP output, MODOP output and IFIP inputs to allow the

user to add matching networks. The board is configured for an

IF frequency of 130.38 MHz when shipped. There is no differ-

ence between the configuration of the boards with the SSOP or

LPCC package.

Figure 32. IF Output Port Impedance Match Used During

Characterization at ADI

The AD830s are used to provide single-ended to differential

conversion and the appropriate phase shift for the I and Q data

input pins. As a result, a single-ended signal generator can be

used to generate these signals.

This is a broadband lossy output match for the 50 MHz to

350 MHz frequency range. The 4:1 ratio in Figure 32 is an

impedance ratio and not a voltage ratio.

As shipped, the board is configured as follows:

In order to test the power-down modes of the AD6122, locate

the two pin headers on the AD6122 evaluation boards labeled

PD1 and PD2. By open-circuiting the pins labeled PD1, the IF

amplifiers power down. By open-circuiting the pins labeled

PD2, the modulator powers down. Note that the IF amplifiers

and modulator are powered down unless the pins on the two pin

headers, PD1 and PD2, are short circuited.

1. J1 is open and J2 is shorted. This enables the LDO regulator.

The external PNP transistor should remain in place even

when the regulator is bypassed (the Pin LDOB is pulled up

by the transistor).

2. X11, X25, X18 and X26 are shorted and X12, X14, X19

and X21 are opened in order to connect the output of the

modulator to the input of the IF amplifiers.

The IF input port impedance match used during characteriza-

tion of the AD6122 at Analog Devices is as follows:

3. L4 and L5, the roofing filter components are optimized for

an IF frequency of 130.38 MHz.

4. R14, R15 and R16 set the attenuation between the modula-

tor outputs and the IF amplifier inputs to 20 dB.

5. PD1 and PD2 are pulled low by the jumpers on the two pin

headers. To power down the chip, set PD1 and PD2 high by

removing the jumpers.

In order to look at the modulator and IF amplifiers separately,

disconnect the output of the modulator from the input of the IF

amplifiers. This is accomplished by short circuiting X12, X14,

X19 and X20 and open circuiting X11, X18, X25 and X26.

Figure 31. IF Input Port Impedance Match Used During

Characterization at ADI

This is a broadband lossy match used for characterization over

the 50 MHz to 350 MHz frequency range. All dBm references

in the characterization data collected using this match are refer-

enced to 1 kΩ. Note that the 1:8 ratio in Figure 31 is an imped-

ance ratio and not a voltage ratio.
