SDR platform can simplify MIMO radio design

The attraction of software-defined radio (SDR) is that it allows a single hardware design to support communications across a variety of formats, protocols, and frequencies, including GSM and LTE basestations, and supporting MIMO (multiple input/multiple output) designs. A basic SDR architecture can look relatively simple, at least “on…

Device optimises gain at microwave frequencies

Gain equalisers from Knowles Capacitors are designed to compensate for module gain slope at microwave frequencies. The thin film devices provides slope correction from DC to 18GHz of greater than 3dB. They are designed for superior, repeatable microwave performance to compensate for gain roll-off and VSWR mismatch losses and…
