RF Front-End ICs
Analog Devices offers RF Front-End ICs for phased array antenna solutions. These RF Front-End ICsare placed right at the antenna element and can quickly switch between transmit and receive functions in radar applications. The power amplifier on the transmit side is highly efficient operating in short pulse durations. The low noise amplifier on the receive side has a low noise figure with high linearity so that it won’t distort the incoming return signal. The RF Front-End IC also incorporates a high performance switch to toggle between the transmit and receive paths. Highly integrated planar phased array antennae need small form factor solutions, and Analog Devices has integrated the switch, low noise amplifier, and power amplifier into a small surface mount package as well as the decoupling capacitors, providing an optimal solution.

CATV Separate Raman Amplifier
RFA4000
Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Amplifier is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. Raman amplifier is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

Full Band Noise Figure and Gain Test Extenders
STG-06-S1
Full band noise figure and gain test extenders are offered to extend noise and gain measuring capabilities up to higher millimeterwave frequency ranges. These extenders are designed to interface with noise and gain test systems that have an input IF of 10 MHz to 1.6 GHz, such as the industry standard Keysight 8970A/B, N8975A and Maury MT 2075B. The noise figure and gain test extenders include a high-performance, solid-state noise source (STZ series) and a full waveguide down converter (STC series), which consists of a Faraday isolator (STF series), full band mixer (SFB series), frequency multiplier, and IF amplifier. A frequency source with an output signal in the frequency range of 10 to 20 GHz is required as a local oscillator for the down converter. The noise source is automatically powered on and off by the noise figure meter.

VDI Millimeter-Wave Frequency Extension Modules for PXA, MXA, EXA Signal Analyzers
These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.
