描述 Description

DESCRIPTION
The 5503 is a low cost, high performance direct conversion receiver (DCR) specifically designed for digital wireless applications. The DCR architecture provides a receiver design with fewer external components than the conventional dual conversion approach. The 5503 is designed to operate over an input frequency range of 950 to 1450 MHz. The device accepts an input signal in this frequency range and down converts directly to baseband. The local oscillator signal is generated by a completely integrated phase lock loop that is fully programmable through a standard serial port interface.FEATURES
