Switch Arrangement and Apparatus

摘要

A switch arrangement is described which enable the design of a flexible front end allowing many individual and combinations of frequency band allocations to share a single antenna simultaneously. An apparatus using the switch arrangement is also described. The switch arrangement provides a single pole switch for each set of band specific filtering. The band specific filtering is connected to the pole of a respective single pole switch. The single pole switch has contact points enabling connection to of the filtering to an antenna switch both with and without a frequency selective component in the signal path. The frequency selective component allows sharing of the antenna by two or more frequency band allocations to enable simultaneous use of different radio access technologies, MIMO or Carrier Aggregation through a single antenna. When not required the frequency selective component can be switched out of the signal path to reduce insertion loss.

主权项

1. A switch arrangement for connecting at least one frequency division multiplexer selectively in a signal path for at least two frequency bands, the switch arrangement comprising:
a first single pole switch having:
a pole for connection to filtering for a first frequency band,a first contact point, anda second contact point; and a second single pole switch having:
a pole for connection to filtering for a second frequency band,a first contact point, anda second contact point; wherein the second contact point of the first single pole switch is connected to or shared with the second contact point of the second single pole switch, thereby providing a single connection for a filtered terminal of a frequency division multiplexer which is shared by the first and second single pole switch.
