Digital Attenuator

Announcing Custom MMIC New Digital Attenuator Product Line from DC-40 GHz

Courtesy of Custom MMIC : Announcing Custom MMIC New Digital Attenuator Product Line from DC-40 GHz

We are excited to launch 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.

Table 1 summarizes the eight new products are now available covering up to 40GHz, with 0.5, 2 and 4dB step size options. Die and QFN packaged versions are available. The CMD281CMD282CMD281C3 and CMD282C3represent initial offerings for coarse control 2 bit DSAs with 2 and 4 dB step control. The CMD279CMD280CMD279C3 and CMD280C3 are the more traditional 0.5dB step control devices with 15.5dB range (5 bit). All devices are single control line per bit.
