The LA01-001 60 dB digital attenuator operates between 400 and 500 MHz with a maximum RF input power of 20 dBm. Maximum VSWR is 1.4:1 and insertion loss is 1.4 dB or less. Accuracy is at least ± 0.5 dB over 36 dB and switching speed is 1 µs or less. Intermodulation distortion is 60 dBc, phase balance is ± 3 deg., and amplitude balance is ±0.5 dB. The attenuator operates from +5 and -15 VDC supplies and meets requirements for shock and vibration specified in Mil-STD 810F.
