The CMD280C3 from Qorvo is a Space-Qualified Variable Attenuator with a frequency range of DC - 18 GHz. It has an attenuation range of 15.5 dB and an attenuation sensitivity of -5 - 0 V. This attenuator has an input P0.1 dB of 24 dB and a switching speed of 25 ns. It requires a DC supply of -5 V and an impedance of 50 ohms. This digital attenuator has a low insertion loss of 3 at 10 GHz and a wide attenuation range with an attenuation accuracy of typically 0.1 dB step error. It is a negatively controlled, wideband GaAs MMIC 5-bit attenuator housed in a leadless 3 x 3 mm surface mount package. This RoHS-compliant, Pb-free attenuator is ideal for applications such as Electronic Warfare (EW), Radar, Space, Satellite Communications (Satcom), Test & Measurement, and Phased Arrays.
