The MAX2530 receiver RF front-end IC, using Maxim's advanced SiGe process, was originally designed for cellular-band and PCS band operation. For 450MHz CDMA, the NF (noise figure) and the IIP3 (input third-order intercept) of the low noise amplifier (LNA) are very critical in considering the sensitivity, and the single-tone desensitization effect. This technical note gives the tuning method and...

Simulated design and analysis of a new simple multi-band microstrip antenna is presented in this paper. An introduced design covers the requisite bandwidth for GSM/DCS/PCS/UMTS cellular phone system and IEEE Wireless Local Area Network (WLAN) standards: 802.11n, b/g (Wi-Fi), Bluetooth. Light weight, low-cost, plain configuration and multi-band functionality are the advantages. All results of th...

The spectral characteristics of the fluorescence Rhodamine 6G (Rh6G) molecules doped into different layers one-dimensional photonic crystals (PCs) have been studied at various detection angles. PCs differ in position band gap (PBG) with respect to Rh6G luminescence spectrum. A computation method density PC`s electromagnetic modes proposed. and computed relative versus wavelength compared for ex...

The fascinating optical properties of photonic crystals (PCs) have lead to numerous new devices or ways to improve existing device characteristics [1]. Photonic crystal slabs (PCS) are of particular interest due to their strong resonant behavior and three-dimensional light confinement, while being compatible with standard semiconductor technology. In this work, we present a photodetector within...

This paper describes the design and simulation by HFSS simulator of a probe-fed Planar Inverted-F Antenna (PIFA) for the use in PCS band [1850 MHz 1990 MHz]. A methodology based on parametric simulations (parameters are ground plan dimensions, height of radiating plate, feeding point position, shorting plate dimensions and positioning) was used to design optimized antenna. The simulation allowe...

Mobile stations in high-tier Personal Communication Systems (PCS) are intended for high-mobility users and must thus operate in fast-changing environments. The first generation of high-tier PCS in North-America will be based on existing digital cellular standards including IS-I 36 TDMA. Moreover, dual-band receivers will be needed for extensive roaming. Adaptive equalizers were devised for IS-5...

We exploit theoretically the occurrence and tunability of photonic Bloch oscillations (PBOs) in one-dimensional photonic crystals (PCs) containing nonlinear composites. Because of the enhanced third-order nonlinearity (Kerr-type nonlinearity) of composites, photons undergo oscillations inside tilted photonic bands, which are achieved by the application of graded external-pump electric fields on...

Computer simulation is a more convenient and faster method obtaining photon correlation spectroscopy (PCS) signal. Based on orthogonal inverse wavelet transform (OIWT), a new simulation method is developed. This method considers that PCS signal of a single scale is composed of several subband signals with different characteristic. According to the relationship of power spectrum of PCS signal an...

We demonstrate the occurrence of nonlinear Bloch waves in metallic photonic crystals PCs . These periodically structured filaments are characterized by an isolated optical pass band below an effective plasma gap. The pass band occurs in a frequency range where the metallic filament exhibits a negative, frequencydependent dielectric function and absorption loss. The metallic losses are counterba...
