This High-Speed Switched-Bit 63-dB Attenuator has insertion loss of 4.3 dB or less, VSWR of less than 2:1, and attenuation flatness of +/-0.5 dB to 31 dB and +/-1 dB to 63 dB. The Model DA64-63B will handle up to +23 dBm RF input power, operates from +5 VDC at 350 mA, and measures 1 x 0.75 x 0.24 in. Control is provided by TTL.

Like all models in Narda's DA Series of switched-bit attenuators, the attenuation values of the DA64-63B are guaranteed to be monotonic, and the unit is hermetically sealed. It operates over a temperature range of –54 to +95 C, meets MIL-STD-202F for humidity (95 h at 95%), shock (76G for 6 ms), altitude (50,000 ft.), vibration (0.06 in. double amplitude or 15G), and thermal shock (5 cycles). Its SMA female connectors are removable, making the attenuator suitable for drop-in mounting.
