IA4432 ISM Transceiver
DESCRIPTION
Integration’s I A4432 transceiver is a member of the new EZRa dioPROTM fa mily. While re taining all the a ttractive fe atures o f earli er pr oducts such as h igh integration, low cost, flexibility, low Bill of Materials (BOM) cost, and easy design-in, these par ts ar e targe ted t o m ore so phisticated appl ications an d offe r sev eral enhanced para meters and fea tures, inc luding contin uous fre quency cov erage from 240- 930MHz and output power up to +20dBm. Also inc luded are built- in features like an tenna d iversity algorithm, wak e-up ti mer, low b attery d etector, temperature se nsor, gen eral purpose Anal og t o Dig ital Conv erter (A DC), TX/R X First-In First-Out Buffers (FIFO’s), power-on-reset (POR), and general purpose I/Os (GPIOs). The chip incorporates a high performance ADC in the RX path and digital modem which performs demodulation, filtering, and packet handling in the digital domain making it ideal for configuration to multiple applications. These features simplify the task of th e sys tem designer a nd allow for t he use o f lowe r-end Microcontrollers. A highly efficient +20dBm po wer amplifier (P A) is completely integrated which eliminates the need for a n external PA and mak es the part ideal for Fre quency Hopp ing Sy stems where maximu m range is desire d. The devices comply with FCC and ETSI req uirements wh en u sed in any of the standard IS M bands. On ly a 30MHz crysta l and a limi ted number of pa ssive matching/filtering components ar e necessar y as e xternal com ponents mak ing the device id eal fo r high volume production in applications where size and cost are critical. The IA4432 is a CMOS Radio Frequency Integrated circuit which incorporates all of the transmit and receive functions required for ISM band applications. The chip is designed to operate over a w ide range of frequencies, voltages, and temperature with ex tremely l ow curren t cons umption which makes it ideal for low-data rate battery powered applications.
