Model 651-017-031 is an SMA programmable attenuator from BroadWave Technologies that operates from 800 to 2200 MHz with as much as 31 dB attenuation. The attenuation can be selected with 1-dB resolution and with accuracy of 0.6 dB or 2 percent of the programmed value. The typical VSWR is 1.30:1 while the nominal insertion loss is 2 dB at 800 MHz and 3.5 dB at 2200 MHz. Ideal for automated testing, the 50-Ohm programmable attenuator achieves typical switching speed of 2 microseconds. Other impedance, attenuation, and connector options are also available.
