Document Type and Number:
Japanese Patent JPH06510173
Kind Code:
A
Abstract:
In a radio transceiver (100), an IF stage (110) is formed on a single substrate. A balanced or image rejection mixer (204) having two pairs of inputs and a pair of outputs is integrated on an IC substrate (202). Disposed on the IC substrate are SAW transformers (210, 212 and 214) which provide a desired phase transformation. The SAW transformers comprise piezoelectric layers (228) and metallization layers (230) which are suitably patterned to provide the desired phase transformation and frequency selectivity.
