3. Single tone measurement setup recommendation:

a. Connect an RF signal generator to input SMA connector, J4.

As shown in 

Figure 1-1

, use an RF band pass filter when measuring single tone distortion.

b. The RF signal generator used must support up to 12-GHz signal frequency for testing the TRF0206-SP 

EVM.

c. The TRF0206-SP device input is 50-Ω in the pass-band.

To minimize signal reflections due to impedance mismatch, TI recommends using an attenuator pad of 
approximately 3-dB to 6-dB between the source and J4 SMA input.

d. The EVM outputs are fully differential (or 180° out-of-phase) at J5 and J6 SMA connectors.

The TRF0206-SP device has low output impedance at dc and low frequencies.

e. When connecting to a spectrum analyzer, the differential signal out of the EVM should be converted to a 

single-ended signal using an external passive balun as shown in 

Figure 1-1

.

Usage of an attenuator pad of approximately 3-dB to 6-dB is recommended at the three terminals of the 
passive balun to minimize reflections.

f.

Lastly, it is recommended to properly characterize and account for the insertion loss of RF coaxial (coax) 
cables, attenuator pads, and passive baluns to measure accurate gain and power levels for the device.

4. Matching considerations:

a. TRF0206-SP is a wide-band amplifier and it receives 50-Ω input matching over its operating bandwidth 

up to about 7 GHz. A signal generator or noise source that drives this EVM will have 50-Ω impedance 
over a wideband width. But, if this EVM is driven by a narrow-band driver or a source that has non 
50-Ω matching, then there may be instability issues with the amplifier. To avoid such issues, additional 
matching may be required at the input. For more information, see the 

TRF0206-SP Single Channel, 10 

MHz to 6.5 GHz 3-dB BW, ADC Driver Amplifier

 data sheet.

b. As mentioned earlier, the TRF0206-SP device has low output impedance, and zero-ohm series resistors 

are used in the EVM. When the EVM outputs are connected to a balun, it is recommended to use 
attenuator pads to minimize reflections.
