Abstract
The passive components of a transceiver, such as transmit/receive switches, antennas, inductors, capacitors and resonators, are integrated together on a common substrate to form an integrated passive transceiver section, which, in combination with other components, provides a highly reliable, low-cost, high-performance transceiver. Micro-electromechanical (MEM) device fabrication techniques are used to provide low-loss, high-performance switches and low-loss, high-Q reactive components, and enable the passive transceiver section's high level of integration. The passive components are preferably integrated on a low-cost glass substrate, with transceiver circuits containing active components fabricated on a separate substrate; the separate substrates are interconnected to implement the RF/analog and analog/digital interface portions of a transceiver. Additional MEM switching devices permit multiple, parallel signal paths to be switched in and out of the transceiver circuitry as needed to optimize performance.
