Transceiver for Bluetooth FH-SS 2.4 GHz Systems
PMB 6625/27
BiCMOS IC
Overview
* Bluetooth Transveiver for the 2.4 GHz ISM Band (RF range 2378-2497 MHz) * Part of complete Infineon Bluetooth chipset solution * Completely integrated receiver with outstanding RF performance: best in class sensitivity and blocking * Low current consumption * No external IF filters or RF filters necessary P-TSSOP-38-1 * B6HFC BiCMOS technology, 25 GHz ft * fully balanced self adjusting VCO with integrated varactor diodes for receive and transmit mode * Prescaler and PLL on-chip with 1 MHz charge pump reference frequency * Supply voltage regulators for the VCO and the analogue part * Internal current reference for PLL charge pump to get constant lock-in time * Small outline P-TSSOP-38 package (PMB 6625) or very small VQFN 40 package (PMB6627) * low-if receiver topology solution Benefits: + no IF SAW-filter necessary or RF ceramic filter necessary + reduced component count * 2.5 GHz RF Power amplifier included, output power adjustable with external resistor, Benefits: + No external PA necessary for Bluetooth power class 2 operation + direct interface to power class 1 PA via small matching circuits + reduced RF front end component count * On-chip LNA for optimum sensitivity and blocking * 70 dB RSSI dynamic range, high stability * Data Slicer including specialized offset compensation or analogue output
