چکیده
This article provides a Bluetooth® history from 1994 to the present, as well as the Ericsson® corporation's role in the system evolution. Bluetooth operates in the ISM band between 2400MHz and 2500MHz, using FHSS on 79 channels with 1MHz spacing. This article also describes how to use Bluetooth for long-range systems with 100mW output power. An example details a discrete power amplifier (PA), the MAX2240, and the supporting bias and power control circuitry. This integrated design meets its goals for performance and cost in support of class-1 long-range Bluetooth transmissions.

متن کاملFully-integrated DECT/Bluetooth multi-band LNA in 0.18µm CMOS
The design of a multi-band low noise amplifier (LNA) is the first obstacle towards the design of a multi-standard receiver. In this paper, an approach for the design of a multi-band LNA for DECT and Bluetooth is presented. The formula for a minimal noise factor of a LNA, that takes into account the finite quality factor of the inductors is derived and the full design procedure that facilitates ...

A two-stage self-biased cascode power amplifier in 0.18m CMOS process for Class-1 Bluetooth application is presented. The power amplifier provides 23-dBm output power with a power-added efficiency (PAE) of 42% at 2.4 GHz. It has a small signal gain of 38 dB and a large signal gain of 31 dB at saturation. This is the highest gain reported for a two-stage design in CMOS at the 0.8–2.4-GHz frequen...
متن کاملA Novel and Single Chip Tri-band Low- Noise Amplifier for Wlan, Wifi and Wimax Receivers
In first stage of each microwave receiver there is Low Noise Amplifier (LNA) circuit, and this stage has important rule in quality factor of the receiver. The design of a LNA in Radio Frequency (RF) circuit requires the trade-off many importance characteristics such as gain, Noise Figure (NF), stability, power consumption and complexity. This situation forces designers to make choices in the de...
متن کاملA fully integrated 2.45 GHz 0.25μm CMOS power amplifier
A fully integrated differential class-AB power amplifier has been designed in a 0.25um CMOS technology. It is intended for medium output power ranges such as Bluetooth class I, and has an operating frequency of 2.45GHz. By using two parallel output stages that can he switched on or off, a high efficiency can be achieved for both high and low output power levels. The simulated maximum output pow...
