CHARACTERIZATION SETUPS

Figure 49 and Figure 50 show characterization bench setups

used to characterize the ADRF6701. The setup shown in

Figure 49 was used to do most of the testing. An automated

VEE program was used to control equipment over the IEEE

bus. The setup was used to measure SSB, OIP2, OIP3, OP1dB,

LO, and USB NULL.

For phase noise and reference spurs measurements, see the

phase noise setup on Figure 50. Phase noise was measured on

LO and modulator output.
