SAA-500M18G-20DB-SFF Active

Switch Bit Attenuator

Product Feature

PMI Model No. SAA-500M18G-20DB-SFF is a switch bit attenuator that operates over the frequency range of 500 MHz to 18 GHz. This model provides 20 dB of attenuation when a TTL "0" is applied and less than 3 dB of insertion loss when TTL "1" is applied. This attenuator switches between states in less than 100 ns and maintains a maximum VSWR of 2.0:1 into a 50-ohm impedance. ±5 VDC is required to power the attenuator and it is supplied in a housing measuring 1.0" x 0.7" x 0.35". Other frequency ranges and attenuation values are available.
