Although the basic design is fairly mature, it has been completely revamped thanks to an innovative technique developed by Synergy Microwave Corp. The novel approach is based on subharmonic mixing techniques and is applicable from about 140 to 3000 MHz.

Response Analysis of Second-Order Multi-Band Quadrature ΣΔ Modulators with Applications in Cognitive Radio Devices
In this article, a novel analytical closed-form model is derived for second-order quadrature ΣΔ modulators (QΣΔM) taking implementation inaccuracies of QΣΔM coefficients into account. The model enables analytical examination of the modulator I/Q imbalance effects on input-output relation as well as signal and noise transfer functions (STF and NTF) independently. Thus, the image rejection of the...
متن کامل180-Gb/s (90-GBd QPSK) single carrier transmitter using a Polymer I/Q modulator
We demonstrate high-speed (90-GBd) modulation of a polymer I/Q modulator achieving single-polarization quadtrature phase shift keyed (QPSK) data rates of 180 Gb/s. Introduction In-phase/quadrature (I/Q) optical modulators are key components for today’s coherent optical transmission systems. Increasing the modulation rate and moving to more complex modulation formats is necessary to achieve high...
متن کاملComplex Bandpass ΔΣAD Modulator with Noise-coupled Architecture
Complex bandpass ΔΣAD modulators can provide superior performance to a pair of real bandpassΔΣAD modulators of the same order. They process just input I and Q signals, not image signals, and AD conversion can be realized with low power dissipation, so that they are desirable for such low-IF receiver applications. This paper proposes a new architecture for complex bandpass ΔΣAD modulators with n...
متن کاملOptical Frequency Upconversion Technique for Transmission of Wireless MIMO-Type Signals over Optical Fiber
The optical fiber is well adapted to pass multiple wireless signals having different carrier frequencies by using radio-over-fiber (ROF) technique. However, multiple wireless signals which have the same carrier frequency cannot propagate over a single optical fiber, such as wireless multi-input multi-output (MIMO) signals feeding multiple antennas in the fiber wireless (FiWi) system. A novel op...
