TRF0208SEP/SP Evaluation Module
Description
The TRF0208SEP/SP evaluation module (EVM) is
used to evaluate the TRF0208SEP/SP device, which
is a single-ended input to differential output RF
amplifier available in a 2 × 2mm
package. The device is designed to drive a high-
speed differential input ADC without using a passive
balun.
The board is set up for 50Ω single-ended input
matching. The amplifier has a low output impedance.
The board has ac-coupling capacitors at input and

The basic steps and functions that are required to verify the proper operation and quick setup of the TRF0208SEP/SP-EVM. This document also includes a schematic diagram, a bill of materials (BOM), printed- circuit board (PCB) layouts, and test block diagrams is outlined in this document. Throughout this document, the abbreviations EVM, TRF0208SEP/SP EVM and the term evaluation module are synonymous with the TRF0208SEP-EVM and TRF0208SP-EVM, TRF0208-SEP EVM unless otherwise noted. - Page 3 4. Matching considerations: a. TRF0208SEP/SP is a wide-band amplifier and expects 50Ω input matching over the operating bandwidth up to about 12GHz. A signal generator or noise source that drives this EVM has 50Ω...
- Page 4 3. Make sure the frequency sweep and output power level from the VNA is set within the linear operating range of the TRF0208SEP/SP devices. The resolution bandwidth (RBW) and dynamic range of the VNA can be adjusted to give optimum sweep time for the measurement.
- Page 5 4. If the loss after the device output is significant, then remember to factor the output loss into the NF measurement. Use the Friis equation to calculate the Noise Figure of the device from the total measured NF.

- Page 6 3. Texas Instruments recommends to keep the output power level within the linear operation range of the TRF0208SEP/SP device. For example, if the total desired output power at the device is 8dBm, then set the signal generators such that each of the fundamental output power results in 2dBm per tone. As a general rule, TI recommends to keep the total output power level approximately 6 to 8dB lower than the 1dB compression point.
