New Product Selection Guide from Custom MMIC

Custom MMIC is designer and supplier of the best MMICs in their class. They offer a rapidly growing family (now over 130 die and packaged devices!) of standardized high performance MMICs, while still offering custom design and delivery of unique solutions. 

Breakthrough Ultra Low Noise Amplifier has 0.6 dB Noise Figure and covers 2-6 GHz Frequency Range

Recently released is a new GaAs Low Noise Amplifier (LNA) MMIC with broadband noise figure performance previously only achievable with discrete FET designs. The CMD283C3, with 0.6dB noise figure, is the first in a family of new Ultra Low Noise Amplifiers.

The CMD283C3 LNA covers 2-6 GHz with high mid-band gain of 27dB and output P1dB of 16dBm. The MMIC is housed in a leadless 3x3 mm surface mount package. It operates from a bias supply of +2 to +5 volts and draws a nominal 42mA. The CMD283C3 is ideally suited for S and C band receivers requiring excellent sensitivity, and as a replacement for discrete FET LNA solutions.

Announcing New Digital Attenuator Product Line from DC-40 GHz

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 CMD281, CMD282, CMD281C3 and CMD282C3 represent initial offerings for coarse control 2 bit DSAs with 2 and 4 dB step control. The CMD279, CMD280, CMD279C3 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.
