Description

The AD210-25 is an IC FET digital attenuator consisting of four monolithic attenuators with LSB of 1 dB and a total attenuation of 15 dB with all attenuators connected. Attenuator bits are switched with -5 and 0 V. The AD210-25 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required.Typical applications include cellular, radio, wireless data, wireless local loop and other gain/level control circuits.

All measurements made in a 50 Ω system, unless otherwise specified. 2. DC = 300 kHz. 3. Insertion loss changes by 0.003 dB/°C. 4. Attenuation referenced to insertion loss. 5. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth. *Due to conflict with another company’s product numbering system, Alpha’s attenuator products starting with the letters “AD” are being changed to “AA”.
