DTA-26R5G40G-30-CD-1

PMI Model DTA-26R5G40G-30-CD-1 is a 10-Bit programmable 30 dB PIN diode attenuator with a step resolution of 0.03 dB over the frequency range of 26.5 to 40 GHz. This model operates on a single +15 VDC supply and draws only 50 mA of current. Very high levels of attenuation accuracy of 0.03 dB is achieved. This attenuator provides ultra-fast switching speeds of 300 ns and has an operating input power rating of +10 dBm. This model is supplied in a small, light-weight housing measuring 2.0 x 1.8 x 0.5 inches.
