LNA-WIDE-O Pre-Amplifier Outdoor All-Weather Mast-Mounted Low-Noise Pre-AmplifierAll band Low Noise Outdoor AmplifierFrequency ranges: 25-1300 MHz Gain 23 dB (typical)Input/output impedance 50 OhmInput/output connectors: NPower supply voltage: 12 to 14V DC(max. voltage limits 11 to 20V DC)Supply voltage connector: SO239Current consumption: 60 mANoise figure: 3.0dB typ. This LNA has been designed in order to improve weak signal reception on all scanner bands from 25-1300 MHz continuous. The LNA uses a weatherproof housing with metal baseplate with low-loss N connectors and HD plastic cover that protects the device against the weather. Supply of power is universal, i.e. two methods can be used. 1. Separate cable for DC voltage (thin coaxial cable is recommended which adds to reliability) to the SO239 connector on the LNA baseplate, or 2. supply via the RF coaxial cable. Both methods are equivalent. The LNA is protected against over voltage and against voltage spikes resulting from static

This monograph presents techniques to improve the performance of linear integrated circuits (IC) in CMOS at high frequencies. Those circuits are primarily used in radio-frequency (RF) front-ends of wireless communication systems, such as low noise amplifiers (LNA) and mixers in a receiver and power amplifiers (PA) in a transmitter. A novel linearization technique is presented. With a small trade-off of gain and power consumption this technique can improve the linearity of the majority of circuits by tens of dB. Particularly, for modern CMOS processes, most of which has device matching better than 1%, the distortion can be compressed by up to 40 dB at the output. A prototype LNA has been fabricated in a 0.25um CMOS process, with a measured +18 dBm IIP3. This technique improves the dynamic range of a receiver RF front-end by 12 dB. A new class of power amplifier (parallel class A&B) is also presented to extend the linear operation range and save the DC power consumption. It has been shown by both simulations and measurements that the new PA doubles the maximum output power and reduces the DC power consumption by up to 50%.

Design of RF CMOS Low Noise Amplifiers presents the results of research on a gain-boosted common-gate RF low noise amplifier (LNA) in CMOS technology. The book covers noise analysis, design techniques, prototyping of the LNA, as well as broadband modeling for on-chip spiral differential inductors. Beginning with a technical review of LNA architectures and inductor modeling techniques, the authors then introduce a scalable lumped circuit model for octagonal differential inductors. The effect of high frequency current crowding, i.e. proximity effect, is taken into consideration in the lumped circuit model. Subsequently, the book offers comprehensive noise analysis of the LNA and discusses design techniques for noise reduction. Measurement results for a 2.4GHz CMOS LNA and conclusions are included. The book is intended for anyone who is interested in learning essentials of RF CMOS LNA design and basic mathematics of on-chip inductor broadband modeling. The book is also beneficial to engineers and researchers in CMOS RFIC design ? especially for WLAN, Bluetooth, and emerging wireless communication applications.

This is for one board NOT THE COMPLETE KIT for switching between your remote LNA and power amplifier (up to 2.5Amps with the part list) when a +5 volt control voltage is applied unlike my item number :110805153961that requires a ground . This was intended to be use as a "flip-flop" be used with most any I.F rig that can supply a voltage on transmit,but is not limited to RF applications, but m any other uses can be found as well. The board is professionally made, 1.5 x 1.5 x 0.063 inches, and ca

Low Power Consumption is one of the critical issues in the performance of small battery-powered handheld devices. Mobile terminals feature an ever increasing number of wireless communication alternatives including GPS, Bluetooth, GSM, 3G, WiFi or DVB-H. Considering that the total power available for each terminal is limited by the relatively slow increase in battery performance expected in the near future, the need for efficient circuits is now critical. This book presents the basic techniques available to design low power RF CMOS analogue circuits. It gives circuit designers a complete guide of alternatives to optimize power consumption and explains the application of these rules in the most common RF building blocks: LNA, mixers and PLLs. It is set out using practical examples and offers a unique perspective as it targets designers working within the standard CMOS process and all the limitations inherent in these technologies.
