Broadband Amplifiers

The model 15S5G7 (15 W) and model 30S5G7 (30 W) amplifiers operate in the 5 to 7 GHz frequency range. These broadband amplifiers are well suited for testing WiMAX components because of the amplified signal the models produce is virtually indistinguishable from the signal generator’s output. Since the linearity of the amplifier signal is as strong as the signal generator there is no interference with adjacent channels. In addition, the units’ high peak-to-peak power ratio means the amplifiers deliver more useable power.

Thermal Design Software

Version 3.0 of the FLO/PCB thermal design software, FLO/PCB for Allegro provides a link to Cadence® Allegro® PCB Editor software that allows designers to simply call up a menu item on the Cadence software and, with a few mouse clicks, generate a thermal model of their design. The FLO/PCB/Allegro interface transfers information about the PCB’s geometry and components needed to perform thermal analysis. This includes the number of metallic layers, the type of each layer such as signal or power or ground plane, the coverage of copper on the board, and the location and power dissipation of each component. The interface also allows the user to select the appropriate layer used to derive the physical extents of the package.

EDR with Loopback Test Mode

Bluetooth V2.0 + Enhanced Data Rate (EDR) options are available for the R&S CBT and R&S CBT32 RF testers. Fitted with the EDR option, the testers allow all measurements – with the exception of EDR C/I performance – to be performed without any external equipment or PCs. With regard to EDR receiver tests, the option supports the loopback test mode in accordance with the specification. The loopback test mode verifies the receiver sensitivity of an existing Bluetooth link under virtually realistic conditions. Like the basic versions, the R&S CBT and the R&S CBT32 with EDR option feature high measurement speed. Lab tasks can thus be handled more quickly, reducing test times and costs in production.
