Abstract
A paging receiver system is provided that can be integrated as one function of a multi-function electronic card device adapted for insertion into a portable computing device. The paging receiver system preferably includes a frequency agile receiver for receiving paging signals, a driver-less interface for communicating the received paging signals to the computing device and a platform-transparent memory for storing the received paging signals. The frequency agile receiver includes a frequency synthesizer for generating a user selectable down conversion frequency that is combined by a mixer to produce a received paging signal at a predetermined intermediate frequency. The driver-less interface multiplexes the received paging signal with the output of a data modem such that the computing device requires only a driver interface for the data modem in order to receive both modem data and paging information. The platform-transparent memory stores paging information received from the computing device in a format that is determined by the platform of the particular computing device into which the electronic card device is inserted. A paging receiver caddy is also provided which can receive…
