Power Amp Is Designed For Bluetooth Class I Radios

Designed specifically for Bluetooth Class I radios, the MAX2240 is a 2.4 GHz, 100 mW power amplifier that occupies just 2.43 mm2 of board space. Its 20 dBm of output power allows users to extend the radio link range to 100 meters, suitable for Bluetooth devices operating in changing environments such as notebook PCs, cell phones, and access points. The chip can also be used for HomeRF, 802.11 FHSS, and other 2.4 GHz proprietary ISM-band radio applications. The device features a digital power-control function, allowing the user to reduce the transmit power in 6 dB steps down to 4 dBm or less, complying with Bluetooth Power Class I specifications. The device also features an integrated 50 ohm matching impedance, further reducing components and required board space. The chip operates on a single 2.7V to 5V supply and draws only 105 mA of current. Pricing starts from $1.75 each/1,000.
