900 MHz analog cordless telephone IC

23 October 2002 Telecoms, Datacoms, Wireless, IoT

Philips Semiconductors' UAA3515A is a BiCMOS integrated circuit that performs all functions from antenna to microcontroller in reception and transmission for both base station and handset of a 900 MHz cordless telephone set. In addition, the implemented programming reduces significantly the amount of external components and adjustments needed.

The single frequency conversion FM receiver includes: integrated low noise amplifier (LNA); image reject mixer; FM detector (10,7 MHz) with: IF limiter, wideband PLL demodulator, output amplifier; received signal strength indicator (RSSI) output; carrier detector (CD) with programmable threshold; programmable data amplifier (slicer) phase.

The receiver baseband has programmable receiver gain; expander; earpiece amplifier with volume control feature; and data amplifier.
