Brroadband, High Intercept Points, Cost-Effective Power-Efficient Double Balanced Mixer (DBM)
Ulrich L. Rohde,Ajay K. Poddar +1 more
TL;DR: The Switching FET DBM demonstrated in this work offers input intercepts points (IIP3) and conversion loss typically 43 dBm and 9 dB respectively with 16 dBm LO power for the frequency band.

Pre-selection filter layout for high frequency receivers
Klaus Danzeisen,Ulrich L. Rohde +1 more
TL;DR: T-filter circuits as mentioned in this paper were designed regarding output as serial acceptor circuits (SE1-SEn) and connected to an input (E) and output (A) switch on or off by switches (D1-Dn) fitted to the side opposite the input for the SEn.
Proceedings ArticleDOI
High-resolution frequency synthesizers over X-band using SILPLL opto-electronic oscillators
TL;DR: In this paper, a frequency synthesizer working at X-band is demonstrated using dispersive optical transversal filter cascaded with YIG filter to electronically fine and coarse tune the oscillation frequency of the synthesized frequency, as a replacement for fixed frequency high Q metallic filter.
Proceedings ArticleDOI
A novel high frequency synthesizer using adaptive injection mode-coupled VCSO for low jitter and low noise applications
Ajay K. Poddar,Ulrich L. Rohde +1 more
TL;DR: In this article, a high frequency digital synthesizer is reported with the intent of lowering following: size, cost, power-consumption, phase noise, jitter, and vibration sensitivity.
Proceedings ArticleDOI
2D periodic structure featuring negative group velocity of bloch waves
TL;DR: In this paper, a 2D, volumetric structure consisting of two dielectric layers, loaded by various metal inclusions on multiple periodic grids and closed by two confining metal planes is introduced in view of advanced dispersion engineering related applications.
