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.
