Local oscillators (LO) are crucial components used in the upconversion and downconversion chains of radar and satellite communications systems. In this post, learn the role of the LO and how its performance can significantly affect the way systems operate. Local Oscillators in Radar Systems A radar signal typically goes through several upconversion steps before leaving the radar antenna. The purpose of upconversion is to shift the signal to a higher frequency. With an upconverted signal, radar systems can resolve targets in greater detail due to improved resolution, since increasing the frequ ..read more

How Can You Analyze Signal Behavior with Crest Factor and Statistical Measurements?
Wireless Telecom Group Blog
by
3M ago
A characteristic of orthogonal frequency-division multiplexing (OFDM) and other digital modulation schemes is high crest factor values or peak-to-average-power ratios (PAPR). High PAPR signals can strain amplifiers, leading to challenges such as waveform clipping, nonlinearities, and increased bit errors. Since crest factor is a single numerical value, the complementary cumulative distribution function (CCDF) can be used to provide a more comprehensive view of signal behavior ..read more

Video Bandwidth and Rise Time – What Do These Terms Mean for Power Sensors?
Wireless Telecom Group Blog
by
4M ago
Peak power sensors have a small smoothing capacitance and low-impedance load across the smoothing capacitors to discharge rapidly when the RF amplitude drops, which results in wide video bandwidths and fast rise time specifications. The RTP5000 Series, for example, achieves a rise time of less than 3 nanoseconds and 195 MHz of video bandwidth.  ..read more
