Abstract

The European radio messaging system (ERMES) is a new generation of full-featured pagers. It defines different pager types for European wide access, from tone only to numeric and alphanumeric. Sixteen channels of 251 kHz bandwidth each are allocated to ERMES, occupying the band from 169.4 MHz to 169.8 MHz. Being a new system, fully-integrated receivers, especially the RF front-end, are not yet available. The chip reported here contains both the RF front-end of a pager receiver, that consists of a 170 MHz LNA with linear AGC, a double balanced mixer and a VCO, and the IF part that consists of an IF amplifier and an IF mixer with output filtering. They are implemented in a 1.2 /spl mu/m BiCMOS process.
