Wideband Fixed Attenuator Family, DIE, DC to 50 GHz

The ENGAT000XX are a line of fixed  precision attenuators matched to 50 Ω. They have attenuation values of 0, 1, 2, 3,  4, 6, 8 and 10 dB. They come in both PI and T style resistor configurations. The  attenuators have gold backside  metallization and are designed to be silver  epoxy attached. Low inductance on-chip vias are utilized and no additional ground  interconnects are required. The RF  interconnects are designed to account for  wire bonds and external microstrip flares  for optimal integrated return loss.  Nichrome resistors with low temperature  coefficients are set up to handle half watt  RF input power levels.
