Addressing the Challenges of Wideband Waveform Generation and Analysis

Satellite and radio waveforms can utilize custom/proprietary formats with modulation bandwidths beyond 1 GHz for increased data rates. Generating custom waveforms with wide modulation bandwidths can present challenges, especially when excellent signal fidelity is required and when distortions must be kept to a minimum. Traditional signal generators can provide...

2.45 GHz High Gain Self-Oscillating Mixer for Simple Short-Range Doppler Radar

A high gain self-oscillating mixer (SOM) for short-range Doppler radars, which meets the needs of simplicity, low power and low cost, is accomplished using a new optimization technique based on SOM’s constant gain curves similar to those of amplifiers....
Modern microwave communication systems have to comply with hard requirements for small size, low cost and reduced power consumption. In order to obtain a final system with such specifications, a commonly used approach is the combination of some functionalities of the system on a single circuit, reducing the number...

Packaged Microstrip Line Diplexer Using SIRs

A compact microstrip line diplexer is reported, which is integrated into a commercial off-the-shelf package for frequency-division duplex wireless communication systems. This diplexer is designed based on the concept of stepped-impedance resonators (SI...
A diplexer is an essential component in frequency-division duplex (FDD) wireless communication systems. Typical requirements of modern diplexers are compact size, good return loss, low insertion loss and high isolation between two passbands. Packaged diplexers are usually preferred because they can easily be integrated into transceiver subsystems. Therefore, the...
