Narda Microwave East Press Release - December 20, 2010
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.
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.
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.
Model DA64-63B attenuator is available from Narda for immediate delivery.
