RF2670PCBA 데이터시트 - RF Micro Devices

Product Description
The RF2670 is a monolithic integrated circuit specifically designed for direct conversion to baseband QPSK receivers. The part provides dual baseband amplifiers with a 70dB gain range (single pin analog input) and separate I and Q RSSI. On-chip programmable baseband filters are incorporated into each amplifier providing 1MHz, 2MHz, 4MHz, or 8MHz bandwidth with a 5-pole Bessel response. I and Q output are available in digital or analog form. The data comparators use a self generated DC reference to track DC offsets in the received signal. The analog outputs have a 500mVpp swing with approximately 1.7V DC offset. A 2.0V reference voltage is also available for A/D converters changing DC bias.
