SGN5210

Product Description: The Signia SGN5210 IC is a low-cost, fully integrated CMOS radio frequency (RF) transceiver, optimized for applications in the globally available 2.4~2.5 GHz ISM band. It contains transmit, receive, VCO and PLL functions, including VCO resonator, thus minimizing the need for external components. The synthesizer is designed for fast hopping and ease of use, requiring only an external RC loop filter. The on-chip reference divider accepts integer reference frequencies between 4~25 MHz, for 1 MHz channel spacing. The transmit section features digitally adjustable output power, ranging from approx. +2 to -32 dBm. Nominal mark and space deviation is ±167 kHz. IQ modulation yields transmit data rates from DC up to 333 kbps (1 Mbps max.). Low in-band spurious signals, and internal Gaussian filtering of the transmit data, ease regulatory compliance. The superhetrodyne receiver is comprised of LNA, active image-reject down-converter, and “low-IF” amplifier/limiter chain...
