Custom MMIC announce the launch of a new product line of GaAs Digital Step Attenuators (DSA).
The DSA family is intended to ease the design of high dynamic range receivers and instrumentation. These applications often must accomplish gain control of 50dB or more. Fine step DSAs (e.g., 0.5dB Least Significant Bit [LSB]) are often used for these applications. However, when a large attenuation change is needed, it is more efficient to use a lower bit count coarse (e.g., 2, 4 or even 8 dB LSB) step DSA MMIC as these parts offer lower insertion loss and fewer control lines for easier design implementation.
