Bluetooth DesignGuide

The Bluetooth DesignGuide is an application package for the Agilent Advanced Design System (ADS) that helps you select the best design topology quickly. It contains various system test benches and reference designs (for example, an optimal low-IF receiver) for the RF portion of the Bluetooth physical layer.

Briefly, it allows for the investigation of system performance (from simple EYE diagrams to BER, the ultimate test) when there are present impairments such as AWGN (Gaussian noise), VCO phase noise, multipath, and/or co-channel / adjacent-channel / intermodulation / pulsed-RF interference. In many cases, the receiver's EYE diagram may be observed in real time during the simulation, while the level of the signal or interferer is adjusted via an interactive slider.

In addition, the DesignGuide addresses some PLL/VCO design issues and helps you select the best demodulator for your receiver.

The contents have been divided into several categories:

• Basic System Test Benches. Tutorial simulations to help you understand the Bluetooth RF segment and to evaluate some filtering options for the transmitter.
  
• Test Benches for 802.11b/g WLAN Interference. System test benches for 802.11b/g WLAN interference effects on Bluetooth.
  
• Component/Subnetwork Evaluations. Simulations to help you understand and validate many of the built-in subnetworks used in the system test benches.
  
• VCO/Phase-Locked-Loop(PLL) Investigations. Simulations of PLL topologies which address timing and noise issues.
  
• Multipath Propagation Test Benches. Simulations that include multipath models for investigating system performance under non-ideal indoor propagation conditions.
  
• System Compliance Tests. System test benches for sensitivity and blocking performance.
  

The following screen capture shows the evaluation of Bluetooth RF synthesizer spurs due to PLL charge pump mismatch. This is the simulation result for harmonic balance analysis.
