This design approach shows how to realize a low-cost scanning receiver for LTE TDD system applications, where fast tuning speed, high measurement accuracy, small size, and low power consumption are critical.
Lowpass filters based on operational amplifiers can provide useful circuit solutions at frequencies to about 50 MHz, although other options are available at higher frequencies.
Designing an accurate digital step attenuator (DSA) with outstanding RF/microwave performance requires careful attention to detail and knowledge of semiconductor process variables.
This silicon CMOS frequency synthesizer achieves high sideband suppression for use in 14-band ultrawideband communications transceivers employing MB-OFDM techniques.
This simple microstrip antenna features a coplanar-waveguide feed and a U-shaped structure in its radiating element to provide a strong notch for interfering signals at 5 GHz.
