The MMS004AA from Microsemi is a MMIC voltage controlled attenuator that operates from DC to 50 GHz. The attenuator is ideal for high frequency and broadband applications in test equipment, commercial and military systems. It has an insertion loss of less than 5 dB, attenuation of 27 dB and can handle up to 6 dBm of power (P1dB). The attenuator is especially suited for applications needing a large amount of adjustable attenuation and fast attenuation control from DC to millimeter frequencies. The MMS004AA performance is controlled by two bias voltages, Vseries and Vshunt. The bias voltages control the match and attenuation of the device when varied between -1V and +0.5V DC. It is available as a die that measures 1640 x 920 mm.
