Integrated passive transceiver section

An RF/analog and analog/digital (A/D) interface portion of a transceiver, comprising:

• a first substrate,
• a plurality of passive components fabricated on said first substrate, said passive components comprising:
• at least one antenna,
• at least one micro-electromechanical (MEM) transmit/receive (T/R) switch arranged to route signals to and from said at least one antenna, said MEM T/R switch comprising a top electrode positioned on the top side of a cantilever arm, a contact electrode affixed to the bottom side of said cantilever arm, a bottom electrode positioned on said substrate, and a gapped signal line positioned on said substrate below said contact electrode, said cantilever arm extending over said bottom electrode such that, when an actuation voltage is applied across said top and bottom electrodes, said cantilever arm is electrostatically drawn toward said substrate and said contact electrode bridges said gapped signal line to create a continuous signal path, and
• at least one component arranged to form a filter,
• said passive components interconnected to implement a passive transceiver section,
• a second substrate, and
• a plurality of active components fabricated on said second substrate, said active components comprising:
• at least one modulator for converting the frequency of signals routed to said at least one antenna,
• at least one demodulator for converting the frequency of signals routed from said at least one antenna,
• said active components interconnected to implement a portion of a transceiver,
• said active components on said second substrate being interconnected with said passive transceiver section to form the RF/analog and the A/D interface portions of a transceiver.
