Model 651-049-033 is a voltage controlled programmable attenuator originally developed for test applications. This 50Ω attenuator has a frequency range of DC – 100 MHz. Attenuation range is 0.5 – 33 dB in a 0.5 dB steps with attenuation accuracy ± 0.5 dB or 2% of programmed value. Insertion loss is 0.8 dB maximum while VSWR is 1.35:1 maximum. Input power is 1 watt average with supply voltage +12 Vdc @ 30 mA nominal per section. The RF connectors are SMA female, and the control solder terminals feature feed-thru capacitors to prevent leakage. Other impedance, attenuation ranges and RF connector types are available.
