The 75P-225 from JFW Industries is a Relay Programmable Attenuator that operates from DC to 2150 MHz. It has an attenuation range of 0 to 63.5 dB in 0.5, 1, 2, 4, 8, 16, and 32 dB steps with an attenuation accuracy of up to ± 1.0 dB. This attenuator has an insertion loss of less than 2.2 dB and can handle an input power of 0.5 W with a VSWR of less than 1.50:1. It has a switching speed of 10 ms and can withstand 300,000 cycles per relay. This attenuator requires a DC supply of +12 V and consumes 33 mA of current (per relay). It is available in a module that measures 8.13 x 1.56 x 0.97 inches and has BNC, F-, or N-type female connector options.
