SAA-500M18G-20DB-SFF Active

Switch Bit Attenuator

PMI Model SAA-500M18G-20DB-SFF is a switch bit attenuator that operates over the frequency range of 0.5 to 18 GHz that provides 20 dB of attenuation when a TTL "1" is applied and <3 dB of insertion loss when TTL "0" is applied. This attenuator switches between states in <100 ns and maintains a maximum VSWR of 2.0:1 into a 50 Ω impedance. ±5 VDC is required to power the attenuator and supplied in a housing measuring 1.0" x 0.7" x 0.35".
