TRF1108 Evaluation Module
Description
The TRF1108 evaluation module (EVM) is used to
evaluate the TRF1108 device, which is a differential
input to single-ended (D2S) output RF amplifier. The
device is designed for applications that require a
D2S conversion when driven by a digital-to-analog
converter (DAC)
The board is set up for 100Ω differential input
matching. The amplifier has a low output impedance.
The board has ac-coupling capacitors at input and
output. The EVM is ready to connect to a +5-V power
supply, signal source, and test instruments for the
measurements.

BiCMOS process and is available in a space-saving, WQFN-FCRLF 2mm x 2mm package. The TRF1108 operates on a single 5V supply with an internally set common-mode voltage for ac-coupled applications. Dual supplies with an externally set input common-mode voltage enables dc-coupled applications. - Page 3 RF band pass filter as shown in Figure 2-1. b. The RF signal generator used must support up to 12GHz signal frequency for testing out the TRF1108 EVM. c. The TRF1108 device input is 100Ω differential in the pass-band.

- Page 6 ) at the device. 3. TI recommends that the output power level is within the linear operation range of the TRF1108 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.
