RF ASIC MAXIM Semiconductor

Maxim's ASICs enable you to "lock up" or Protect a circuit-design intellectual property (IP). These can be used for creating solutions for Cellular, Handheld, Satellite Datacommunications, GPS, etc.

Maxim chips have a wide range of uses, especially in easily resolving Complex Analog and Mixed Design Requirements.

RF and Wireless ASICs - Maxim

"A two-stage 1.9GHz monolithic low-noise amplifier (LNA) with a measured noise figure of 2.3dB and an associated gain of 15dB was fabricated in a standard silicon bipolar transistor array. It dissipates 5.2mW from a 3V supply including the bias circuitry. Input return loss and isolation are -9dB and -20dB, respectively."

ViPEC Network Analyzer

ViPEC is a powerful tool for the analysis of high frequency, linear electrical networks. It takes a schematic description of the electrical network and performs a linear analysis in the frequency domain.

ViPEC Network Analyzer

The output is in the form of port parameters (S, Y or Z) with results presented on a user defined grid, Smithchart or table. It can also be used to compute other characteristics like stability factors and group delay.

ViPEC Network Analyzer

ViPEC supports various lumped elements (capacitors, resistors etc.) as well as distributed networks like transmission lines, microstrip and stripline structures. Two port data files are also supported (e.g. the 2-port frequency parameters of various RF transistors as supplied by the manufacturer). The component library is under constant development with new elements added at regular intervals.

Microchip PIC - Wireless Connectivity Design

Ethernet communication solutions offer access to the most widely deployed networking system. The TCP/IP protocol, which is at the core of this technology, allows total location independence and interoperability to any embedded application.

Microchip PIC - Wireless Connectivity Design

Ethernet. TCP/IP, ZigBee, MiWi - "The emerging standard for flexible wireless networking specifically designed for embedded control. ZigBee supports stars, clusters and mesh networks of up to 64k nodes. Microchip supplies a free stack that supports a variety of transceivers."

MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module.

Has a integrated PCB antenna, matching circuitry, and supports ZigBee too. Connects to many PICs via a 4-wire SPI interface. You can design wireless sensor networks and home automation systems.

The MRF24J40 is an IEEE 802.15.4 Standard compliant 2.4 GHz RF transceiver. It integrates the PHY and MAC functionality in a single chip solution.

A frequency synthesizer is clocked by an external 20 MHz crystal and generates a 2.4 GHz RF frequency. The receiver is a low-IF architecture consisting of a Low Noise Amplifier (LNA), down conversion mixers, polyphase channel filters and baseband limiting amplifiers with a Receiver Signal Strength Indicator (RSSI).

Radiocalc or dBcalc - Conversions RF Engineering

Besides classical functions and dB conversions, RadioCalc includes a converter of Power to field strength commonly used for EMC/EMS test-set-up. Also impedance can be represented as a function of reflection coefficient (somehow like an electronic Smith-chart). This and many other functions are obtained by clicking into the arrow of the "Conversion off" window.

Radiocalc - Convertisseur Radio Universel

Thanks to RadioCalc the different dB charts are obsolete by computing the ratios of Power (W) or Voltages (V) according to dB = 10*log(P2/P1) ou dB = 20*log(V2/V1).

Just for a trial : type 100/10 (or just 10) and push the dB button as the 'W' mode is chosen, the result will be 10 dB, then choose the 'V' mode by clicking in the V button (in the Quick dB window) push again dB, the result is now 20 dB.
