Narda High-Speed Switched-Bit 63-dB Attenuator Offers Extremely High Performance from 2 to 6 GHz
HAUPPAUGE, NY – December 20, 2010 -- Narda, an L-3 Communications (NYSE: LLL) company, today introduced the
Model DA64-63B switched-bit attenuator, which offers the high level of performance required in electronic
warfare and radar systems as well as precision automated test equipment.
Model DA64-63B is a 6-bit device that provides attenuation of 0 to 63 dB in 1-dB steps, and operates from 2 to
6 GHz with a switching speed of 30 ns (50% TTL to 90% RF) and rise and fall times of 10 ns. It 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.
attenuator is available from Narda for immediate delivery.
