AR Worldwide introduces two new models in its line of S series broadband amplifiers. Models 700S1G4 (0.8 to 4.2 GHz) and 800S1G3 (0.8 to 3 GHz) have rated power outputs of 700 and 800 W respectively. Both the 700S1G4 and the 800S1G4 have low levels of spurious signals and high linearity, making them suitable for use as driver amplifiers in testing wireless and communication components and subsystems. Each can be used as a test instrument covering multiple frequency bands, and they are suitable for a variety of communication technologies such as CDMA, W-CDMA, TDMA, GSM, etc. They are also suitable for EMC test applications where high power and undistorted modulation envelopes are desired.
