Suited for electronic warfare and radar systems as well as precision automated test equipment, the DA64-63B switched-bit attenuator 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 part 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. Offering a temperature range of –54° to 95°C, the devices also 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 (Contact company for pricing — available now.)
